GAS CAP on 2005 Saturn Vue

SENSOR LIGHT CONTINUES TO GO ON EVEN THOUGH SATURN REPLACED GAS CAP. EVERY TIME GET GAS THIS LIGHT GOES ON. i TIGHTEN THE CAP TIGHT AND STILL THIS OCCURS, THEY HAVE RUN COMPUTER TEST AND CAN NOT UNDERSTAND WHY THIS HAPPENS. WHAT CAN I DO...THIS IS SO IRRITATING.

Asked by for the 2005 Saturn Vue
Is there any way you could tell me which fault code is stored in the computer memory of your 2005 Saturn Vue when the light comes on? Is it the "check engine" or check gas cap" light coming on?
Thank you so much for responding. It is the gas cap, the dealership replaced the gas cap for free....light still on, they say I now need a "smoke test" at the cost of $200-$250 just for a diagnosis...unbelieveable

I had this problem today. After reading this post, I went to tighten the cap. The cap had a note that said click it three times. I did and the light went out. Thank you for saving me money.
