The check engine light comes on when your car’s computer detects an issue within the powertrain. It can indicate a major or minor complication, but ignoring it definitely makes the problem worse, leading to costly damage and repair. You can avoid all the hassles if you know the reasons of the light coming on. Nevertheless, it sometimes does not turn off despite solving the glitch. In that case, you will need to know how to reset it.
4 Ways To Reset The Check Engine Light
It could be annoying if the red light of the check engine indicator does not go away. If it happens, you won’t be able to find out any trouble in the future. Your vehicle’s computer is at fault here, and it needs a little fix to resolve the issue.

Use A Scan Tool
Plug an OBD Code Reader to the OBD port in the fuse box. Turn it on by pressing the power switch and then holding down the ‘read’ button on the scanner. Give it some time to scan your engine for any error codes. The screen will display the error code(s) and you can erase them with the help of the ‘erase’ button. Don’t forget to turn on the ignition before deleting the codes.
Apply The Battery Disconnecting Technique
Identify the battery under the hood and disconnect its positive power cable with the help of a wrench. Wait for at least 15 to 20 minutes before turning on the ignition and do it for three times. It will delete the emissions and readiness flag data from the computer’s memory. Now, reconnect the positive cable and switch on the ignition again with the key. The check engine light is supposed not to turn red this time.
Turn The Ignition On And Off
It’s a repeat of the previous technique without disconnecting the battery. You just have to put the key into the ignition and turn it on and off for three times in a row with the gap of a second in each step. After you are done, drive the car to see if the light is reset.
Let The Check Engine Light Go Off By Itself
It’s the easiest process because you need to do practically nothing except for driving the vehicle as usual. The computer system in most cars keeps rechecking the problems that activate the light in the first place. If it’s a minor issue such as a glitch with the mass airflow or O2 sensor, it may fix automatically, and the light will go dark. However, if it still stares at you after three days, you have to apply the methods mentioned above to reset it.
What If The Check Engine Light Returns?
It can come back within a few days or weeks, which may signal a major complication. If it keeps happening despite following the resetting procedures, you should take the car to a service center and have it diagnoses by a professional mechanic. Such a repair shop uses more sophisticated tools to find out the exact problems.
