4 DIY Ways –Reset Check Engine Light

*  It is essential to be sure that the light isn’t on because your engine really does still have a problem.

1. Drive Your Car and Let the Light Go Off by Itself

Most onboard computers will recheck whatever problem caused the check engine light to activate multiple times. Drive your car as you normally would. If the check engine light is still on after three days, your problem may not have been fixed

2. Turn the Ignition On and Off

This forces the computer to refresh its saved state through a reboot. Simply place your key into the ignition and turn it on for 2-3 seconds, then turn it off for 2-3 seconds. Repeat this step three or four times.

3.    Disconnect and Reconnect the Battery

Disconnect the positive power cable to the vehicle battery. Leave the battery disconnected for at least 15 minutes. Then put your key into the ignition and turn it three times to the “ON” position. This will clear the emissions data from the vehicle memory as well as the readiness flag data. Reconnect the positive battery cable and turn the key in the vehicle ignition. Wait one minute and the check engine light error should be gone.

4.    Use an OBD2 Scanner

Before you reset check engine light, you need to get that problem fixed as soon as possible so that you don’t damage your car in the long run.There could be an emissions problem, a faulty oxygen sensor, a bad catalytic converter, or even a bad intake manifold.

Check engine lights aren’t something to be taken lightly.  If you don’t know how to fix it, you could end up spending a lot of money getting your car fixed unnecessarily.

Will The Check Engine Light Reset Itself?

If a minor fault caused the light to come on, and stops occurring, then yes, it will clear itself. If the condition indicates a bigger problem turned the check engine light on, then it will stay on until reset or cleared manually.

A good example of a fault that will clear itself, is having low brake fluid. I experienced this and would only have the light come on when stopping hard over time, which triggered the sensor. After the force of stopping subsided, the sensor state returned to normal, and the code / light was cleared. Also, timing issues will usually clear themselves if they do not persist.

Keep in mind!
