6 TIPS TO MAKE YOUR CAR TRAVEL READY THIS HOLIDAY SEASON

Here are a few easy ways you can prepare your car for a road trip:

  1. Check Tire Pressure – This step is essential because you can get better gas mileage when you drive on properly aired tires. Not only will you be able to save some money in doing this, but you’ll decrease your risk of a dangerous blowout as well.

  2. Have Any Warning Lights Diagnosed – If you have some warning lights on your dashboard that you’ve been ignoring up until now, you’ll want to have them diagnosed before a long-distance trip. .

  3. Look at Your Fluids – The fluids in your engine enable it to run correctly, so you don’t want to be without them! You’ll want to check your oil, antifreeze, power steering fluid, brake fluid, transmission fluid, and windshield washing fluid.

  4. Replace Old Windshield Wipers – Putting up with inefficient windshield wipers gets old after a while. Replace old ones before a trip, so you don’t end up frustrated, or unable to see, in the rain.

  5. Notice Unusual Brake Noises – If your brakes have been making a whining or grinding noise recently, it’s probably time to take your car in for brake service.

  6. Check Your Lights – If your headlights aren’t working, visibility while driving at night can be an issue. If your brake lights or turn lights are burnt out, you pose a danger to both yourself and other drivers. Have a spotter assist you in checking your headlights, taillights, brake lights, and turn lights.

8 Signs of Auto Transmission Failure

While an auto transmission failure isn’t a death sentence for your car, it can definitely be a major repair. It usually means a lot of downtime and a huge bill. Your transmission is an amazing work or art. Ok, you might not want to mount it over your fireplace, but you have to admit that it is rather fascinating how all these gears and bearings and interestingly shaped parts are put together to create a system that actually propels your vehicle from Point A to Point B. Some people say that the transmission is the second most important part of the car, next to the engine. But, I respectfully disagree. It’s really a team effort – you can’t have one without the other. While, I guess you can, but they are rather useless independently. They are like the heart and the brain of your car. They work together. So, a problem with your transmission can affect the operation of the engine. And if you don’t fix it, you could have even bigger issues to deal with.

But, contrary to popular belief, an auto transmission failure doesn’t always have to be scary (are you breathing a sigh of relief now?) While it can be a costly adventure, in a lot of cases, the problem is actually quite minor. And, as with anything mechanical, if you catch the problem early enough, you may be able to avoid more serious issues. But, you can’t always count on mechanics to offer you the easy way out. After all, they are in the business to make money. So, when they see a woman walk through their doors, they get dollar signs in their eyes.

Transmissions are complex and complicated systems so fixing them usually requires a professional. But, that doesn’t mean that you have to accept whatever diagnosis you are handed. If in doubt, get a second opinion. Or, better yet, learn how to recognize the most common signs of auto transmission failure and how to rule out simple fixes before you authorize an expensive auto transmission repair. Replacing or rebuilding may be necessary, but it is important to check out other possibilities first. You never know, some basic knowledge could save you thousands of dollars.

Signs Of Auto Transmission Failure

  • Slippage. This is when your motor is revving but your car isn’t responding. It’s similar to the way your vehicle would react if your tires were slipping on ice or stuck in the snow. You are pushing the gas pedal and you can hear the engine roaring, but you don’t seem to be getting anywhere. Slippage affects your transmission’s ability to propel the car forward and if it gets really bad, eventually you may not move at all.
  • Leaks. Check under your car on a regular basis to make sure there aren’t any leaks. In most automatic transmissions the fluid is red, so if you notice a colored puddle on the ground, you should probably have your car checked out. In fact, if you notice any puddle at all (except for the ones made from your AC) you should investigate further.
  • Smells. If your fluid level is low, your transmission can overheat. When your transmission or transmission fluid gets too hot, you may notice a burning odor. Check your fluid level and add if necessary. You may also want to find out why the level was low in the first place.
  • Sounds. Knocking, whining, humming, buzzing, clunking, and grating can all be signs of transmission problems. These sounds can be a result of wear and tear, but they also can mean a low fluid level.
  • Delayed Engagement/Lack of Response. Sometimes your transmission doesn’t want to do what you ask when you ask. Just like your kids, right? But, unlike your children, there are times when motherly negotiations (aka bribing) will not convince your vehicle to behave properly. There are varying degrees of delayed engagement, and sometimes we are in danger of letting things for too long.
  • Rough Shifting. Again, your car should transition between gears smoothly. If you notice shaking, jarring, bumping, clunking, or abrupt/hard shifting, this may be a sign of transmission problems.
  • Fluid Color. Transmission fluid is red, clear, and has a slightly sweet odor. Look at a sample of new, clean fluid so you know the correct color and smell. If the fluid in your vehicle is murky, dark, or dirty, this could be an indication of problems. Sometimes changing the oil or doing a transmission flush will fix the issue. In some cases, more serious repairs may be necessary.
  • Check Engine Light. Sensors in your car can pick up small vibrations or other problems even before you notice them. The check engine light could be a warning of transmission problems, especially if you are also experiencing any of the above signs.

10 Ways to Care for Your Automatic Transmission

Avoid costly transmission repairs. Here are 10 tips for keeping a car with an automatic transmission in good condition

Depending on the type of vehicle you drive and its age, transmission repairs can be costly. Sometimes it’s impossible to avoid having a transmission repair specialist service your vehicle particularly if you’re subjected to a total breakdown.

But there are things you can do to extend the life of your automatic transmission and prevent transmission failure. Read our checklist of top 10 transmission maintenance tips:

1. Check your transmission fluid periodically. On many cars, light trucks, and SUVs, checking the transmission fluid is as easy as checking the oil: with the engine idling, pull out the dipstick, wipe it off, insert it again, wait, then pull it out to get an accurate reading. If the fluid level is low, you may have a leak. The fluid itself should be a bright red color, clear, and it should smell sweet. If it’s murky, dark coloured, or smells like rotting fish take it to a transmission repair specialist to look things over.

2. Use the right type of transmission fluid. Always consult your vehicle’s owner’s manual to determine what type of transmission fluid you should use. If after doing so you’re still not sure, pop in to a Mister Transmission and ask a professional.

3. Have your engine’s cooling system serviced. Your vehicle’s cooling system helps prevent the engine from overheating. But did you know it also ensures the transmission fluid pumping through the gearbox is cooled too? It’s more likely you’ll need a transmission repair before your engine completely overheats. Make sure your cooling system is in optimal condition.

4. Get your transmission flushed regularly. Changing the transmission fluid in your car is best left to a professional. Consult your car’s owner’s manual, but in general, get your vehicle’s transmission flushed once a year. How long the transmission fluid in your car will last depends on the vehicle’s operating temperature and how much driving you do.

5. Don’t change gears while your car is moving. Bring your vehicle to a complete stop before changing gears from ‘drive’ to ‘reverse’ or vice-versa. Failing to do so simply puts strain on your transmission and after awhile it can lead to a serious problem.

6. Let your car warm up before you drive. Who among us has hopped into the driver’s seat, started the engine, put the car in drive and motored away? (Full disclosure: I’m as guilty as you are) Always allow your engine a few minutes to warm up before you begin to drive, especially during the winter months.

7. Don’t drive on a spare tire for an extended period of time. Mismatched tire sizes, or driving with a small spare tire over a long period of time is a no-no. Not only will it do damage to other parts of your vehicle such as ruin the wheel alignment, after a while it puts unnecessary strain on the transmission.

8. Regularly change the transmission filter. That’s right: your car’s automatic transmission may have a filter, and it needs to be changed from time to time. Whether or not you’re driving a car that has a transmission filter depends entirely on the make and model. Most newer vehicles don’t have a transmission filter but those that do should be changed each time you get your transmission flushed.

9. Avoid using your vehicle for towing. Using your car to tow heavy loads, particularly in hot temperatures, can cause the transmission fluid to oxidize or burn, and in turn, do a lot of damage to the transmission.

10. Have your transmission inspected annually. Having a certified transmission repair specialist conduct a diagnostic check of your transmission for leaks and other abnormalities at least once a year, as well as checking the transmission fluid’s level, color, and smell periodically is smart preventative maintenance.

Easy hacks to keep your car clean

Car cleaning and maintenance can sometimes get a bit difficult – but not for you! In this post, we’ve mentioned 10 easy hacks you can use to keep your car clean.

1. Use baby wipes to clean your windshield and windows  

Who knew baby wipes could also clean your car’s windshield and windows without any streak. Baby wipes are made of soft materials, and they won’t harm your car’s windshield. However, use it only when absolutely necessary and don’t have access to a dedicated glass cleaning product.  

2. Roll down your windows while cleaning them   

Most car owners simply spray the cleaning product onto the windows and wipe them. They tend to miss the dirt on top of the window. This dirt, if left uncleaned, can streak down on a rainy day. Make sure you roll down the window and clear off the dirt stuck on the top too.   

3. Use dryer sheets to remove bug splat  

Have you ever returned from a road trip with bug splats all over your car’s exterior? Use the dryer sheets to remove those bug splats without any hassle. However, if the stain is deeply embedded, we recommend you visit a car wash near you to clean it.

4. Leave the sponge – take the microfiber towel!  

Close your eyes. Imagine someone washing a car. What are they cleaning with? Do you see a sponge in their hand – if yes, we have a piece of news for you. You should never use a sponge to wash your car because dirt can get stuck on the pores, and when used on your car’s exterior, it can cause scratches. Even new sponges are abrasive. We’d highly recommend using a car-specific wash mitt or a microfiber towel while washing and detailing your car.   

5. Baking soda to remove odor   

All you need is a pinch of baking soda to remove any unpleasant odor from your car’s seats and doormats. Sprinkle the baking soda on the floor mats, seats, and other surfaces, wait for a little while and vacuum it.    

6. Use vinegar for odor removal  

Vinegar is also an excellent odor remover because it has the quality to neutralize foul smells. Pour white vinegar into a cup and leave it overnight in your car.  

7. Apply peanut butter to remove tar spots     

Apply peanut butter – not the crunchy ones – on the tar spot and wipe it with a towel. It may sound weird but, it does get the job done. Thanks to the peanut butter’s oil content, it can easily remove the tar from your car’s exterior.   

 

7 Car Noises You Should Never Ignore

Hmm. Purr. Vroom. Modern engineering has made driving a car easier on the ears than ever.

But there are some car noises you don’t want to hear, because they can signal trouble. Every once in a while, roll down the windows and start listening for “any sound that is odd,” says Mike Peth, director of technical training at Ohio Technical College in Cleveland. “You know your car, so you can often pick up something that may become a problem.”

1. A sound like a coin in a clothes dryer

What it means: If you hear something rattling around inside a wheel at low speeds (and then stops as you drive faster) it could be a loose lug nut inside a hub cap. That might mean your wheel wasn’t tightened properly the last time it was removed and replaced. Take your car to a mechanic ASAP.

2. Brakes squealing, grinding or growling

What it means: If you hear a squealing noise, your brake pads or shoes might be nearing the end of their service life and must be replaced. If they grind or growl, get your brakes checked out immediately. It could be a sign that pads are so worn that metal is touching metal—a serious problem that could affect braking efficiency.

3. A finger-snapping, popping or clicking sound when you turn

What it means: If you have a front-wheel-drive or all-wheel drive vehicle and hear this sound when you turn or corner (but the noise stops when you steer straight) one or both of the constant velocity (CV) joints on your front axle could need replacing.

4. A rhythmic squeak that speeds up as you accelerate

What it means: If you have rear-wheel or four-wheel drive and hear this sound, the culprit could be the universal joint (U-joint), which are found in pairs and are components of the driveshaft. Get it checked by a mechanic immediately.

5.  A howling, whining or even “singing”

What it means: This is usually a sign that your bearings—tiny metal balls that help parts rotate smoothly—aren’t doing their job. But which ones? If you have front-wheel drive, and the sound changes as you turn left, right and back again, it’s likely your front-wheel bearings; a gradually growing, steady howl signals rear-wheel bearings. If you have rear-wheel drive and the whine gets louder as you accelerate, your differential, which allows your wheels to spin at different rates when needed, could be leaking fluid. Get it fixed immediately.

6. Rhythmic clunking, tapping or banging from under the hood

What it means: There could be a serious problem with valves, connecting rods or pistons. Get to a mechanic ASAP.

7. Squealing under the hood at start-up or when accelerating

What it means: This could come from worn or loose accessory belts that drive things like your power steering pump, air conditioner compressor and alternator. With newer cars, it may point to the serpentine belt, which drives multiple accessories at once, and is relatively easy and cheap to fix.

Tips To Keep Your Car Sensors In Good Condition

The sensors in your car are a safety feature; they help you maintain good driving habits. By keeping your car sensors in good condition, you can avoid unnecessary damage to your vehicle and even to you and your passengers.

For example, if the airbag failed to deploy during an accident, this could cause serious injuries or even death. To prevent this situation, you have to keep your car sensors in top condition.

1.Diagnose Electrical Problems

The first thing you should do is to diagnose an electrical problem as soon as it occurs. If your car runs rough or doesn’t start or runs rough, the battery is likely weak and needs to be replaced.

If your vehicle starts but doesn’t run smoothly after that, the problem can be with the starter or alternator.

When diagnosing a loose battery connection or a faulty fuse, it is good to test each individually. You may use jumper cables to test for shorts between two points on the circuit board. If this doesn’t work, you have to go through more troubleshooting steps until you find out what’s wrong with your car.

2. Check The Battery Cable Connections

Next, you should check the battery cable connections on the ground and underbody of your vehicle. This will allow you to know if one of them is loose and causing issues with starting your car.

If you notice that they are all okay, replace them with new ones after checking out their condition to see if they are old or damaged.

3. Clean Regularly

Another thing you should do is to always clean your car sensors. Doing this can remove dust and dirt, which can cause issues with the sensor’s ability to function correctly.

You can use a soft cloth or cloth diaper to wipe down the surface where the sensor sits. You should also ensure that there are no dirt particles or oil on the surface. If any residue is left behind from previous cleaning attempts, you might want to do one more attempt before moving on to something else.

4. Not Leave The Sensor In Direct Sunlight

Sunlight is harsh on electronic devices, especially car sensors. If you leave your car outside for long periods, the ultraviolet rays will damage your car’s sensors. For example, it might cause an anti-lock braking system to stop working correctly or a cruise control system to slow down or stop altogether.

If you want to keep your car sensor in good condition, you should avoid leaving it in direct sunlight. Instead, park your car under a shady tree or inside a garage to prevent damage from occurring.

5. Keep An Eye On Your Car’s Oil Level

Keeping up with your car’s oil level is essential because it can affect how well your car sensors work. If there are too many contaminants in the oil, it can damage the sensors and make them less effective at detecting obstacles. The same is true if there isn’t enough oil in the engine. An overfilled machine can have the same effect on your car’s sensors as a small amount of contamination in the oil.

Thus, you must check your car’s oil level regularly and monitor how much it drops. If it keeps dropping, the sensor may be wrong, and you should take it to a mechanic immediately.

6. Adjust Sensor Alignment

If your car’s sensors are misaligned, it can cause issues with the system. Also, they will need more time to pick up on vibrations. This can affect the performance of the airbags and seat belt tensioners.

The sensors are aligned by adjusting the sensor bracket on each side of your car. To change the sensor brackets, you’ll need to remove them from the vehicle and rotate them in either direction until they are flush against each other. Once you have adjusted them, replace them into your car and then test drive to ensure that everything works correctly now that they’ve been aligned perfectly.

 

 

How to Clean Headlights

Headlights are an important safety feature on your car, whether you’re driving at night or in inclement weather. Unfortunately, headlights can become foggy and dirty, which dulls their brightness and makes them less effective at lighting the road. Plastic headlights can become foggy as a result of UV ray exposure and damage from the elements.

If your lights don’t appear as bright as usual, try one of these methods to clean them. There are several ways to restore clarity to your headlight lenses.

Use liquid soap, baking soda and vinegar

With liquid soap, baking soda and vinegar, you can restore your headlights in a few simple steps. Keep in mind that this method may not fully brighten very yellowed, foggy lights, and you may need to repeat the steps several times.

Begin by cleaning dust from the headlights with a microfiber cloth. Add a tablespoon or two of liquid soap to a bucket. Add enough water to thin the soap to a watery solution. Using another clean microfiber cloth, clean the headlight with the soap solution. The idea is to get the lens as clean as possible before using the baking soda and vinegar. Rinse the soap off the headlights using a spray bottle of water and use a towel to dry the headlights.

Mix 1 to 2 tablespoons of baking soda with enough white vinegar to form a thick paste. Using a dry-cleaning cloth, gently polish the headlamp with the paste. Rinse the paste off with the spray bottle of water and repeat until the lens is clean and clear.

How to clean car headlights with toothpaste

Before beginning, remove dust and grime from the headlight with a clean cloth. Then, spray the headlight with water using your spray bottle. Using an old toothbrush, apply toothpaste to the lens and gently scrub. Use regular white toothpaste, not the gel type. Rinse with water until toothpaste is gone and the headlight is clear.

How to clean foggy headlights using a headlight restoration kit

These kits can be expensive, but they’re effective and safe for restoring headlights. Use them as directed; typically, you’ll just need to apply the cleanser and rinse. A kit may also come with waxing compounds to protect the lights.With any method, use soft cleaning cloths made of microfiber. These are gentle and can help to prevent scratching. They also typically don’t leave stray fibers behind. Learn how to restore your headlights.

How to Clean Your Car Engine

Knowing how to clean your engine is an important part of vehicle maintenance, and it can save you money. Tidying up under the hood helps extend the life of belts, hoses and other components. Plus, it’s easier to spot leaks, tears and other damage on a clean engine. Check out the steps below to properly clean your car engine, and be sure to consult your car’s operation manual before you get started.

1. Eliminate any residue

Your car’s hood, grille and vents are prime areas for dirt buildup. Blow them out with compressed air or clean the areas with a wire hand brush.

2. Get the temperature just right

Next, let your engine warm up to a moderate temperature – not too hot. This will help soften grease buildup in the engine compartment.

3. Know what to cover when cleaning your engine

Plastic sandwich bags come in handy when it’s time to clean up your car. The parts to keep covered when cleaning your engine are:

  • Electrical wiring
  • Sensors
  • Spark plug openings
  • Alternator
  • Distributor

Secure the baggies with tape. To protect your battery, cover it or simply remove it.

4. Don’t forget the drip pan

Place old towels on an absorbent mat under the engine’s oil drip pan to catch any hazardous waste.

5. Give the engine a good spritz

Thoroughly spray the engine compartment with an engine cleaner, avoiding the wiring you bagged and taped. Since petroleum cleaners can damage rubber and vinyl components, consider a citrus or water-based degreaser. For parts that seem extremely oily or greasy, let the cleaner soak in for 15-30 minutes and repeat if necessary.

6. Rinse and unwrap

Once the engine cleaner has done its job, lightly rinse engine and components with water. Remove the bags you used to protect the wiring. Once the towel or mat is dry, dispose of it properly. And if you removed the battery, don’t forget to replace it.

7. Remove excess moisture

Blow away excess water in the engine compartment with compressed air.

8. Dry out the interior

Lastly, turn on your engine and let it run until warm. The heat will help dry the hard-to-reach areas.

10 Reasons Why Your Car Won’t Start

It’s one of the worst things that can happen to a driver. You turn the key in your car’s ignition, perhaps hear a few alarming noises, and then…nothing. Whether in the parking lot after dinner, in your driveway before work, or even at the rest stop after you’ve stopped for snacks, there’s never really a good time for your car to not start. It’s usually indicative that your car needs some kind of repairs, and even when it doesn’t, it creates a serious logistical challenge on your hands.

What do you do when your car won’t start? After calling roadside assistance and getting you and your car to a safe location (preferably an auto shop), you’ve got to figure out why it’s not starting. Here are ten possible reasons why your car won’t start.

1. Bad or dead battery
The most common reason cars don’t start is a dead or faulty battery.1 Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire.2 If something’s wrong with your battery, your car engine won’t turn over. There are other symptoms that may indicate a dead battery, but checking if your engine turns over at all is always a good first step.

The good thing about dead batteries is that you don’t need a professional to get your car going again. Jumping a car battery is something that anyone with a base level of know-how can accomplish. Battery jumps are temporary solutions though, and new batteries can be expensive, so it’s best to just take good care of your battery. For more on how to do that, check out these tips for avoiding a dead battery.

2. Bad alternator
A bad alternator goes hand-in-hand with a bad battery. The alternator recharges the battery and keeps the car’s electrical systems running after the car has started. If you’ve got a bad alternator, you don’t necessarily have a bad battery, but you certainly might not have a functioning one. Any bad alternator should be replaced, so be sure to look out for any signs of a bad alternator.

3. Starter motor
Dead batteries or alternators aren’t the only things that can stop your ignition from functioning. If something is wrong with the aforementioned starter motor that receives the electrical signal to crank the engine, your car may not respond to the turn of your key.

Common symptoms
One of the easiest ways to tell if your starter motor has a problem is to check if your lights come on when you turn your key in the ignition. Turning your key turns your battery on, so if you’ve turned your key all the way and the lights come on, but the engine doesn’t turn over, your starter motor could be the culprit. Any signs of electrical failure could also indicate the starter motor needs help. Repeatedly trying to use a starter motor that has been subject to a blown fuse could cause it to overheat and emit smoke.3

4. Bad ignition switch
The ignition switch is another step on the road that leads from turning your key to starting your engine. It plays a crucial role between your battery and starter motor, carrying power from the battery to the engine.

Common symptoms of a bad ignition switch
If you have a bad ignition switch, you won’t hear the starter motor working to start the engine. You also might experience some electrical issues since the ignition switch effectively activates your car’s main electrical systems. Flickering or dying dashboard lights are a prime example. You may also have difficulty turning your key in the first place.4

5. Spark plugs
If your car doesn’t start, it’s possible that its spark plugs are old or dirty. Spark plugs that have become defective in any way can lead to reduced gas mileage, lack of acceleration, engine troubles like misfires, and yes, even difficulty starting your car at all.5

6. Broken distributor cap
It’s not necessarily the spark plugs’ fault. The distributor cap routes power from the engine’s ignition coil to the spark plugs. Broken or malfunctioning distributor caps can cause your engine to misfire, activate the check engine light, cause strange noises, and, of course, prevent your car from starting.6 Make sure there is no moisture under the cap and replace it immediately if it’s broken.

7. Bad timing belt
Your timing belt is another component that is integral to a functioning engine. The timing belt rotates the engine’s cam and crankshaft in unison, causing the cylinders to fire at the appropriate times.

Common symptoms of a bad timing belt
If something is wrong with your timing belt, you may hear ticking noises from your engine, strange disparities in your engine’s revving, or your engine may not turn over. Replacing your timing belt is a piece of maintenance that needs to be performed on a semi-regular basis, so if you notice any issues that could be tied to it, don’t hesitate to call your mechanic.7

8. Jammed steering lock
Ever gotten into your car and found that you can’t even turn your key? If you’ve experienced this, it’s likely that your steering lock is jammed. Your steering lock activates when someone tries to move the wheel while the key is not inserted in the ignition as an anti-theft measure.8 However, it can occasionally serve as an anti-driver measure by accident.

If your steering lock jams, try to wiggle it left and right and then gently turn it in whichever direction allows some movement. Once the lock is unjammed, you can turn the key in the ignition normally.

9. Clogged fuel filter
If fuel can’t reach your engine, your car is going to have a difficult time burning it. As obvious as that sounds, you might not realize that the fuel filter is preventing your car from starting.

Common symptoms of a clogged fuel filter
You may notice an array of fuel-related troubles, ranging from sputtering to poor gas mileage, and, of course, difficulty starting. Your fuel filter should be replaced every 30,000 miles, so if yours is coming up on that milestone and your car doesn’t start, it’s worth checking and replacing.9

10. Empty fuel tank
No one wants to run out of gas, but if you do, the silver lining is that there isn’t anything wrong with your car. If your tank is empty, your best bet is to procure a gas can and give your car the couple of gallons it needs to start, and get to a gas station.

What to Do When the Check Engine Light Comes on

The dashboard of a car is full of mysterious lights that run the gamut from warning to a friendly reminder. Most of these lights remain dark most of the time, and when they do emerge, few people understand all of them. The check engine light is cardinal among these cryptic signals, with many possible reasons for its appearance and more than a few ways to make it go away. But what does the check engine light mean? Despite its varied reasons for appearing, there is an overarching rationale to it, and an important one at that. Understanding what to do when the check engine light comes on can mean the difference between a dangerous mechanical issue and an easy fix at the auto shop.

 

What does the check engine light mean?

Let’s start with what the check engine light doesn’t mean. It’s easy to see a warning light come on and hit the panic button, but the check engine light doesn’t usually warrant immediate concern. If you’re driving along and it turns on, you don’t usually need to pull over and call for help. You should take the light as a sign it’s time to get to a mechanic soon, though. The check engine light is a part of your car’s onboard diagnostics system, which monitors variables like engine speed, fuel mixture, and ignition timing. When that system detects a problem it can’t correct on its own, it responds by switching on the check engine light.

 

What does the check engine light look like?

So, your car’s diagnostics have detected a problem, what are you looking for? A yellow check engine light will appear on your dashboard, though the shape may vary based on the car you’re driving. In some cars, the check engine light literally reads “check engine” and nothing else, while in others it appears in the shape of an engine, occasionally with the word “check”. The light’s appearance may also vary depending on the problem. A solid check engine light indicates a less urgent issue, while a flashing check engine light signals a problem that requires immediate attention. Some cars also show a red check engine light if the problem is severe.

 

Common reasons the check engine light comes on

Engine problems

There is a slew of engine problems that can cause your check engine light to come on. Most are minor and cause your car’s fuel economy and emissions rating to decline, however, some can develop into major issues if unchecked. Engine misfires, for example, will cause poor fuel economy and performance in the short run, but can eventually lead to outright engine failure.

Damaged or loose parts and equipment

Any parts that are damaged, loose or missing will trigger the check engine light. Loose gas caps are a common example of this, though this problem does not pose any serious harm to your car.

Sensor issues

If your diagnostics system detects faults in any of your engine’s many sensors, your check engine light will come on. Some common examples are your oxygen sensors, which measure unburned oxygen in your exhaust system, and mass air flow sensors, which measure the amount of air entering your engine to determine the amount of fuel it needs.2

Transmission problems

As the master of your engine’s power output, your transmission can also trigger the check engine light if it malfunctions. Transmission problems can lead to increased tailpipe emissions.3

Overheating

If your coolant has not been changed properly it can eventually cause your engine’s thermostat to degrade, eventually overheating the engine. If this happens, your check engine light will activate.

 

How long can you drive with the check engine light on?

Many of us willfully ignore the check engine light until we see the symptoms of whatever caused it to turn on. That’s a tempting strategy, but it’s not wise. Your issue may be minor at first but develop into a major problem, as is the case with a bad catalytic converter. Even if the problem is merely reducing your fuel economy, that’s still additional emissions and expenses out of your pocket that a quick trip to the mechanic could fix. In either case, you should have your car evaluated as soon as possible.

 

What should you do when the check engine light comes on?

Turn your car on and off

Turning your car on and off three times consecutively may reset your car’s trouble codes. It’s worth trying this before taking your car in for service.2

Check gas cap

Yes, sometimes it’s as simple as tightening your gas cap. Be patient after doing this, as it may require several trips before the light resets.

Perform a diagnostic test

Many newer cars come with onboard remote diagnostics systems. These systems can report trouble codes and schedule a service appointment accordingly.

Reduce your speed

If your check engine light blinks on while you’re driving, a good first response is to reduce the strain on your engine. Lowering your speed will help. This is especially important if the check engine light is blinking or if it is red, indicating a more urgent issue.

Reduce load

You can also reduce the strain on your engine by reducing the haul it’s carrying. If you’re towing anything, you might want to stop.1

Wait and see

It’s not advisable, but you can always wait and see what happens. Most check engine lights do not need to be addressed immediately, and worsening problems will make themselves apparent. If your car’s situation is becoming more urgent, you’ll probably see or hear the signs.

Visit a mechanic

If you haven’t discovered the reason your check engine light is on, it’s probably a good question for your mechanic. You should take your car in for service as soon as possible.
