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.

After a long day at work, you get into your car and look forward to an adventure on the open road. However, as soon as you turn the key in the ignition, a bright yellow check engine light appears on your dash. Be composed. The indicator light serves as a warning, but it doesn’t always signify that something significant is wrong.
What the check lights are communicating to you.
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.
Three steps to take when your engine light is on.
When your engine light comes on, one of the first things you should check is your gas cap. Look to see whether your gas cap is damaged, cracked, or loose. Ensure that your gas cap is tightened if it is not. Replace your gas cap immediately if it is damaged. The fuel must not evaporate, of course.
2. Look for overheating or low oil pressure.
Check your gauges and lights for signs of low oil pressure. If your signal light is flashing, you might need to slow down and stop towing. When something like this happens, you must carefully pull over and quickly dial a tow truck.
3. Make a Consultation.

What is the time it takes for the check engine light to go out?
In the majority of car models, the check engine light will go out after you fix the issue. However, it can take a while. Usually, a car needs 1020 successful resettings before the check engine light goes out on its own.
A cycle is when you start your car from a cold start, drive it until it warms up, and then stop.
After 1020 successful cycles, which, as you can imagine, can take a while, the check engine light will reset itself if you are certain that you have resolved the issue that was the cause of the check engine light. As a result, using an OBD2 scanner to reset the check engine light is much simpler.
After tightening the gas cap, will the check engine light come on?
Get out of the car and if necessary, open the gas cap door. Bring a flashlight if it is dark out. You might require the additional light to inspect the gas cap for cracks. Examine the gas cap. Are there any rips, chips, or cracks in it? If so, a straightforward gas cap replacement could be able to fix the issue. It is advisable to look for any tears or cracks that could result in a vapor leak in the seal that is located between the gas cap and the filler tube.
Install the gas cap into the filler tube all the way if you are confident it is in good condition. Once you hear the gas cap click into place, tighten it with your hand. The cap has to be changed if it clicks into place but remains loose afterward.
If the check engine light was brought on by a loose gas cap, it should turn off within a few minutes of driving.
After you’ve experienced the check engine light, pay attention to the dashboard. Your gas cap is too loose if you notice that the light continues turning on and then turning off when you tighten it.
Ordering a replacement gas cap is easy if you discovered that yours is broken or loose. To achieve a snug fit, you must first check sure the gas cap is appropriate for the make and model of your car. Have you ever had a check engine light? If so, why did it happen?
Is it legal to drive with the check engine light on?
As a general rule, you shouldn’t continue to drive if your check engine light is blinking. It is a crisis. It frequently signifies an engine misfire.
The (expensive) catalytic converter will likely sustain the most of the irreparable damage if you continue to drive.
Avoid the cost by having your automobile hauled to a qualified mechanic.
Steady Check Engine Light
If the check engine light stays on, you can continue to drive the vehicle. But only if the vehicle’s vital components, such the brakes and lights, are working.
Watch the coolant temperature and oil pressure warning lights on your dashboard carefully.
Driving with the engine light is on is it safe?
Can a car be used when the engine light is on? You can continue driving for a short distance, but make sure to schedule an engine inspection as soon as you can.
Don’t freak out if the check engine light comes on while you’re driving! Keep an eye out to observe if the car is driving in any unusual ways. Is it safe to operate a vehicle with the engine light on? The performance of the vehicle and the underlying cause of the check engine light’s lighting will determine whether it is safe to continue driving. Simply remember to get your automobile checked as soon as you can when the light comes on. Don’t put off necessary engine maintenance!
You can keep operating the vehicle if nothing seems unusual. Anything from a bad oxygen sensor to a poor MAF sensor could be the root of the problem. It can also indicate that your catalytic converter has stopped functioning.
Here are three steps to help you determine whether it’s safe to continue driving or if you need to stop immediately:
- What else could be wrong? – Your dashboard may also show low oil pressure or overheating issues in addition to the check engine light. Pull over and turn off the engine as quickly as you can if these lights appear. A yellow light indicates an investigation, but other cars have a red check engine light to warn you to stop immediately away.
- Take it easy – If the check engine light is also accompanied by performance issues, reduce your speed and be gentle with the engine. Avoid abrupt shifting and spikes in speed. To avoid a potentially expensive engine repair, attempt to unload as soon as you can if you’re hauling a trailer or carrying heavy equipment.
- If the light comes on after refilling, tighten the cap! Verify that the gas cap is secure. A leak in the evaporative emissions system is being detected by the sensor. Resetting the light may need many engine restarts.
Your car’s onboard diagnostics system is connected to the check engine light, which is intended to illuminate (often in yellow) whenever something goes wrong with any of the parts or sensors. A “trouble code” is used to store issues in the electronic control system and track them back to their origin. Your mechanic can identify the issue and do any necessary changes or repairs using a diagnostic computer.
Does a dreaded oil change set off the check engine light?
It’s an annoying sight. You are aware that you should take your automobile to a repair as soon as possible when the check engine light turns on. These lights may indicate a significant issue or something as straightforward as a loose gas cap. Regardless, figuring out the issue is essential.
An appropriately performed recent oil change is one item that won’t cause a check engine light to come on.
Although oil changes are a necessary part of car maintenance, they won’t do anything to cause your check engine light to illuminate. After changing the oil, if the light comes on, something else is wrong.
Your mechanic has the tools needed to conduct tests and figure out what’s wrong. The following are five of the most typical issues with check engine lights:
How can I tell if the check engine light on my car is serious?

When a situation is critical, the engine light may not blink in some automobiles. If an important problem has been found, red or orange will display in place of yellow on the light.
Bottom line: Whether the check engine light is solid or flashing, you should always have your car diagnosed and fixed. A flashing light signals an urgent situation that need immediate attention. Seek a mechanic’s assistance as soon as you can to protect your car and avoid having to make expensive repairs.
