Hello,
If there is a problem in the vehicle that meets the requirements to illuminate the check engine light, that code will likely be reset each time the vehicle is started and/or driven.
You will need to have the issue diagnosed and repaired before the light will turn off.
We offer estimates for check engine light diagnostics here:
