have you taken it to your parts store yet to have the codes read?they will usually do that for experience with check engine lights usually ends up being a bad egr valve,bad o2 sensor,or a simple fix of a loose or bad gas cap.hope this helps!

Gas cap tightened on? Happened with my 03 if I ever got full service gas. Also, if it did go on randomly it would go off after a few starts.


I have recently had that same problem. I would unscrew the gas cap and then replace it and make sure it is on tight and secure. The light went off. I think I need a new cap, but when I do that it works!
