There is a reason that the check engine light came on. The ECM (engine control module) detects a problem. You can clear the codes with a code scanner but if the problem hasn't been fixed the light will come back on. You need to have the codes read. The codes will help you determine the cause of the check engine light problem. It may be as simple as a loose fuel cap.
