How do I reset or turn off the check engine light?

You can reset the check engine light using an OBD2 scanner with a clear-codes function, but doing so without fixing the underlying problem only hides the issue temporarily. Once the engine runs its self-tests again, the light will return if the fault is still present. Disconnecting the battery is an old method that may also reset the light, but it erases other stored data and is not recommended. The right approach is to diagnose and repair the cause first, then the light clears on its own or stays off after reset. At Motoro Cars in Miami, our ASE-certified, AAA-approved technicians use computerized diagnostics to fix the real problem and properly clear the code.
