Pontiac Aztek Problem Report
Pontiac Aztek Check Engine Light Due to Gas Cap Issue
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
check engine light always on. I had mechanic reset it but it came back on after a week. My gas cap completely broke off, I still have one inner piece I use to cover the gas tank so it is not left open to the elements but people always asked me why there was no cover for the gas cap. I hadn't even noticed when I bought my vehicle. - delilarose
Repaired head gasket. Then two years later had same problem. Decided to replace engine with a used one. This one last another couple years, now head gasket is leaking again causing engine to overheat. Don't get me started! In addition to this problem, we also have to deal with the transmission and replacing the alternator. Total repairs are going to set us back over $8,000.00. I think it's time to dump the Aztek! - Visitor
Lost my gas cap and had to replace it with a generic one that doesn't fit as well as it should. It was fine for about 1000 miles... but as soon as I hit 80,000 on the odometer the Check Engine Soon light came on. - Visitor
It happened twice because I didn't turn the cap until it clicked. After fixing the light went off, although 1 time it stayed on. Fixed by removing cap and driving a few miles and put it back on and light is off - Visitor
Comes on, old cap would not tighten brought a new one, same problem...cap is still loose - Visitor
No a problem, used On Star to check it. Since the '01 had an analog OS, I just tighten the cap again. Still happens occasionally with 122,070 miles. Love this vehicle! - Visitor
