Pontiac Bonneville Check Engine Light Due to Gas Cap Issue

(17 reports)

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

When I put my gas cap on, I have to turn it past being on. I turn it until it clicks several times. Otherwise, my service engine light comes on. -
