Saturn SC2 Check Engine Light Due to Gas Cap Issue

(15 reports)

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

I had the check engine light on in my car, so I took it in to get a diagnostic. The mechanic explained that the car is designed to recycle gas vapors, and if some of those vapors escape through the gas cap, then the car detects that as a leak, and the check engine light goes on. He put a new gas cap on the car and the light's been gone since. -
have replaced my gas cap numerous times since about 50000 miles and keep having the same issue with the CE light and then replacing it again -
Threw a vacuum leak code. Bought a new OEM gas cap. Code no longer appears. These cars are hard to kill...check your oil! -
