Default Check Gas Cap

Hi everyone,

Today I got a message on display "check gas cap".

I checked the gas door and the cap and they both are good.

Is this message for the door or the cap, and what can I do to fix it.

thank you

Known issue. There's actually nothing wrong.

You can smear the seals around the cap with silicon grease or wd40 and see if that helps. If not, you can go to your dealer and talk them into replacing the cap under the warranty.

I did both (in that order) and the error still returned a couple weeks later. The next time I was at my tuner's shop, I just had him remove th error via his software. Problem has not returned

If your Vette is no longer under warranty, you can purchase a gas cap from Gene Culley (GMPartsHouse.com) at this link:

Good luck!

I think the caps are part of the emmisions and should be covered under warranty for 50K miles (?). If you cap leaks air in California you will not pass the SMOG inspection. It might be something to look into. BTW, I'm not sure about the 50K miles, but that is what Honda and Toyota have.

Disconnecting the battery, that will reset the computer
Sometime the computer gets conflicting info and will throw a code

Weird...this happened to my '05 about a week ago. I read the past threads on the forum...decided to splurge for a new cap. Picked it up at dealer (around $20 with tax). I put it on and the "Check Gas Cap" message was still on. Having been alerted by the Forum that this could happen, I reset it and the next time I started the car.....no message and I've been 100% fixed ever since.
If you look at the cap, it has "cheap" written all over it. No wonder they fail after a while.

If replacing the gas cap doesn't work then you have a crack in the evap line somewhere. It's not hard to fine with the smoke can. It happened to me. Keep getting a reading for the gas cap, replaced it and the DIC said the same thing. It was then I realized I had an evap problem.

This is the only error message that I've gotten on my '05 and it really WAS a bad fuel cap. I had just bought the car from a dealer last year, and hadn't put gas in yet. So when I checked it out it just spun. No click. Local dealer did it under warranty in 20 minutes and code reset. So yes sometimes it really means what it says!
