Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

    The check engine light stays on and periodically the indicator warning flashes saying check gas cap. I have replaced the gas cap, but nothing changed.

    Same issue, engine light is on. It states to "check gas cap." I replaced the gas cap twice and had the dealer to reset the light. Came back on the next day.
