    The check engine light is an indicative that the vehicle's computer has detected a failure on the emission controls system. You will need to retrieve the trouble codes to diagnose the problem. Learn more about it here; http://repairpal.com/check-engine-light

    If you fail to tighten the gas cap to a certain point the CHECK ENGINE light will come on.
