The Check Engine light remains on constantly. My mechanic is baffled as to why this is occurring.

When I bought my car, I bought a locking gas cap. When I took my car to get it fixed, the guy told me to try the old gas cap and the check engine light went off.

NEVER overfill your gas tank. When filling up and the gas hose clicks off at the pump DO NOT fill to max. Also Make sure the gas cap is tight after filling so as not to create a vaccum. Common sense fixes this problem.

check engine light came on. Mechanic checked code, cleared it and suggested we tighten gas cap to at least three "clicks". Three months later problem has not returned

I had to have the gas cap replaced because the light kept coming on and once the cap was changed no more problems.

Tightening gas cap 4 clicks avoids the problem. Replacing the cap solved it.
