You might have requested for assistance with a computer problem if you’ve ever worked in an office setting with an IT department.
Probably the first thing your IT wizard asked was, “Have you tried resetting your computer?”
The analogous repair for a car’s check engine light is the on-off technique. It compels the computer to reboot and restore its previously saved state.
Simply switch the ignition on for 1-2 seconds, then off for 1-2 seconds, using your key. Three or four times through, repeat this step.
If the check engine light is still on after the reset, your car might still be having issues. Think about using the OBD2 scanner to check for the error code or taking your car to a qualified repair.

Drive your vehicle and allow the light to turn off on its own
Driving and time are the first and simplest ways to turn off the check engine light. The majority of onboard computers will check the issue that triggered the check engine light several times. Just like you would usually, drive your car.
After three days, if the check engine light is still on, your issue might not have been resolved, or you could need to use one of the techniques listed below to reset it.
Technique for Disconnecting Batteries
Without a scan tool, disconnecting the battery terminal for 30 to 60 seconds is the most effective approach to turn off the check engine light. In many car models, this will reset the engine control unit.
Remove the negative terminal from the automobile battery first. Then, try to exhaust any remaining electricity in the capacitor of the automobile by sounding the horn for 20 to 30 seconds or turning on the lights. After the electricity has been turned off, park your automobile for 10 to 15 minutes. Once this little period has passed, reconnect the battery terminals, check to make sure they are securely fastened to prevent any potential sparking, and then start your automobile.
After restarting, if your car still displays the check engine light, there may be a significant issue with it or the automobile may have stored the codes. Because some automobile models won’t allow the codes to be reset by cutting the power in this situation, it is strongly advised to check the codes with a scanner instead.
What should you do if the Hyundai check engine light is on?
The check engine light on your Hyundai will come on if the MAF isn’t working properly. Usually, changing your air filter will take care of the issue. Through our parts center, you may place an online order for an air filter. Oxygen Sensor: To assess how much gasoline is being used, this part measures the oxygen levels in the exhaust.
Can my Hyundai be driven with the check engine light on?
We strongly advise not driving your Hyundai while the check engine light is on and setting up Hyundai servicing right soon. The most frequent causes of your check engine light appearing are listed below: You must replace your mass airflow sensor, or MAF.
How long does the check engine light take to turn off?
The check engine light will go away after about three days of steady driving. Cars function in cycles. The glow should go after finishing 10 to 30 cycles, which should take three days. As I mentioned earlier, your car goes through a cycle of turning on, driving till it warms up, then turning off once more.
Keep in mind that the issue that caused the light to turn on must be resolved in order for this procedure to be effective. Try several approaches if this one doesn’t work; if not, bring the automobile to an experienced mechanic.
Will an oil change cause the check engine light to go out?
You could simply take a few minutes to fix the difficulties if the low oil pressure appears to be the cause. To see if the system determines the pressures on its own, run the engine for a few minutes.
The Check Engine Light ought to illuminate as the fresh oil is pumped through the engine. If it doesn’t, something more significant is going on.
If the low oil pressure was only temporary, you might need to use an OBD2 scanner to reset the check engine light, which could turn off the warning light.
What sensor is to blame for the check engine light?
Oxygen sensors are frequently the culprit behind “check engine” lights. All cars built after 1980 come equipped with this sensor, which is part of the emission control system. The oxygen sensors are used to make sure that your engine is operating at its best efficiency and burning the right amount of gasoline. In order to control your emissions, it also works with your catalytic converter.
Oil ash can eventually cover the oxygen sensor or O2 sensor. As a result, it won’t be able to properly monitor the fuel (fuel system) and oxygen mix in your engine (can cause the check engine light to illuminate). Additionally, the air conditioning system could be harmed.
Simply visit your neighborhood auto repair shop to have your oxygen sensor repaired; components and labor typically cost around $200.
If you’re handy, though, you might try replacing it on your own. Online stores provide O2 sensors, and your owner’s guide should contain comprehensive instructions on how to replace an oxygen sensor on your own vehicle.
What does a check engine light that is solid yellow indicate?
To monitor what is happening inside your car, the onboard diagnostic system interacts with various components of it. A warning indicator light is sent to your dashboard when there is a problem with the electronic control system to let you know there is a problem. Depending on how the light appears on your dashboard, you can determine whether it’s a serious or minor problem.
It’s not usually a significant problem, but the constant yellow light is alerting you to take a look and solve the small problem as soon as you can. The engine of your car is misfiring if the light is flashing, therefore you need to look into the issue right away. If you don’t think it’s safe to drive, you don’t need to stop immediately away. However, you run the risk of damaging the engine of your car if you ignore the bright or flashing light. If your engine light illuminates, we advise performing the actions listed below.
What does a check engine light mean?
The light could indicate a minor problem, such as a broken gas cap, or it could indicate a more serious problem, such as an engine that is misfiring. It frequently indicates that you will need to take your vehicle to the dealership for repairs and to have the light turned off.
What causes the check engine light to appear most frequently?
The oxygen sensor is the same way. This important component measures the amount of unburned oxygen present in your car’s exhaust, and if there is too little or too much, it may harm other engine components. Every time an oxygen sensor fails, a check engine light will come on. In fact, it’s among the most frequent causes of a check engine light appearing while you’re operating your car.
Will changing the gas cap the check engine light off?
The check engine light can occasionally be set off by a loose or damaged gas cap. The fumes that are emitted are usually the cause of this. Simply take off and reinstall your gas cap. If you start your automobile, the engine light can already be back on.
How far should I drive when the check engine light is reset?
How many miles should I drive after resetting the check engine light for examination if I’m trying to turn off a check engine light? While there are many factors that can affect this, there is a rough distance that you need travel in the car before you can determine whether the light will go out.
Of course, various factors may affect how many miles you must travel. These may consist of:
- The car’s overall dimensions
- The state in which it is
- The number of miles per gallon
Next, we’ll go through each of these so you can get a better idea of what your specific vehicle might need to turn off the check engine light. The distance you must travel to observe what is happening might be affected by all of these factors and more.
Typically, you must travel 50 to 100 miles after clearing the computer in your automobile. Hopefully, this will permanently turn off the check engine light. If it doesn’t, a more serious factor may be making this item switch on. To determine what the actual issue is, you might need to take it to a professional.
There are several cars available that allow you to tower above obstacles without sacrificing the comfort of a compact automobile. We’ve compiled a list of our favorite new sedans with high ground clearance as a result.
Why is my engine light on when there doesn’t seem to be a problem?
The on-board diagnostic system uses the “check engine” light to alert you of problems. However, that something might be any number of other things, great or tiny. It might turn on due to a minor issue, such as a gas cap that is loose or broken. It might also indicate a serious engine breakdown.
What year did Hyundai recall its engines?
Model Year 2013 and 2014 Hyundai Sonata vehicles with 2.0 liter and 2.4 liter gasoline direct injection (GDI) engines produced at Hyundai Motor Manufacturing Alabama will have their engines inspected and, if necessary, replaced as part of a safety recall by Hyundai in the United States.
An orange engine light: What does that mean?
Your car uses chimes, icons, and messages to communicate with you even if it cannot speak. The orange, engine-shaped icon that is typically displayed in the instrument cluster is one that you should never disregard. When the onboard computer of the vehicle notices an issue, it switches on.
If you see it, don’t freak out—it doesn’t necessarily mean you have to give the nearby mechanic your next salary. A check engine light can occasionally be caused by simple issues that are easy to resolve. Likewise, don’t disregard it and have it examined as soon as you can.
The top 10 issues that frequently cause a check engine light are listed below. Remember that the fault code that first triggered the light is saved in your car’s onboard computer, and you can recover it using a straightforward Bluetooth-powered device connected to an app to determine precisely what is wrong with the engine. Long-term savings will result from doing this on your own.
When my orange engine light is on, can I drive?
Even if the engine management light is just a tiny warning symbol, it is still a good idea to be vigilant and investigate any potential problems if it appears on your dashboard. This light can signal a problem that will need to be fixed soon, though it is rarely a warning that your car is ready to come to a grinding halt.
Of course, there’s always a chance that anything is genuinely wrong, so even if everything appears to be in order from the driver’s seat, it’s not worth the risk to ignore an engine warning light. A relatively simple and inexpensive problem may become something far more complicated and expensive if you don’t figure out what’s going on as soon as possible.
Modern cars feature a number of warning lights that occasionally illuminate on the dashboard, but they are typically easy to identify thanks to standardized symbols that denote conditions like low oil pressure or a hot engine. The check engine light is more enigmatic because it can be set off by a variety of systems connected to engine performance.
But it’s simple to identify; it’s one of the lights that flashes momentarily every time you start the car (see figure below). At this stage, unless you have a significant problem that requires quick treatment, the light will typically be orange. For a clearer signal, some autos employ the ‘CHECK ENGINE’ emblem. If your warning light stays on or illuminates while you’re driving, you probably need to take some action. The warning light is meant to turn off after a second or two once the engine fires up.
Although an orange or amber light typically doesn’t indicate that you need to stop right away, some cars feature a red warning light for more serious problems. When the engine management light turns red, it’s time to stop, dial your breakdown service, or at the very least, find out what it signifies in your car’s owner’s manual.
Initial responses can range from immediately pulling over to the side of the road to attending a nearby garage as soon as you are able to get a diagnosis.
