Same problem! Tired of it! How am I suppose to know when I have a REAL problem? lol

My Check Engine Light was going on, too, even though I'd securely tighten the gas cap after fueling. Even after I had the gas cap replaced, it'd occasionally go on. I just live with it.

No matter what the mechanics do, the light will not stay off. It always point to the gas cap. I've gotten it replaced with a new one and the problem continues.

My check engine light comes on every gas tank fuel fill at different levels. I changed my cap and it is still doing it

The gas cap wore out, and I replaced it for about $20.
