I click the gas cap 3 times past the normal clicking & the check engine light still stays one, need help to fix it or find someone who can. Thank you.
I bought this car used at a dealer and drive it 4 days and after my first gas fill up the check engine light went on.
This started about 5 years ago at 25,000 miles, and all I have to do is to turn the gas cap at least 3 turns to make sure that the Check Engine light doesn't come on. If it does and it is shortly after you pump gas into the car, then you know that you haven't turned it past 3 turns on the gas cap. This problem hasn't happened to me since it started 5 years ago.
After the car was serviced. This check engine light came on. Dealership said it was nothing. That was over 30,000 miles ago. Now that the warranty is out, they want to check it. A friend told me the rubber had probably worn out in the gas cap's sensor. To replace the as cap.
Made sure gas cap was tightened and it completed the problem. Gas cover fell off. Have noticed other with the same problem
Check engine light came on... went to mechanic... told to replace gas cap with original from Chevrolet.
I was overseas serving in the military when the recall started, by the time I returned the recall had expired.
Check engine light came on and I know a lot about cars so my first instinct was the gas cap. After 20 minutes of driving the check engine light shut off. I knew it couldn't be my engine because chevy just put a new engine in after the last one cracked down the side, through the block.
Check engine light went on and the repair man said the gas cap wasn't locking so the gas fumes were not being properly cycled through the engine. I just had to get the gas cap replaced; it cost about $25.
