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

    NEVER overfill your gas tank. When filling up and the gas hose clicks off at the pump DO NOT fill to max. Also Make sure the gas cap is tight after filling so as not to create a vaccum. Common sense fixes this problem.

  • I had to have the gas cap replaced because the light kept coming on and once the cap was changed no more problems.

    Was in Florida and the light came on and when I got gas the cap was lose, tightened it up drove for a 1000 miles ant went off. Later same problem tightened it and light went off in a few miles.
