Gas cap light ??
The other day I was driving down the highway and my gas cap light came on. I pulled over took the cap off and put it back on and that didn't make the light go away. I didn't think much of it and a couple days later my check engine light came on (I assume this is because of the other warning?). Ive gone thru 3 tanks of gas since then and my mpg's are the same and the truck doesn't seem to be running any differently.
Any ideas whats going on here and how to fix it?

Gas cap was either loose or has a bad seal. If you have a programmer you can clear the code (or take it to one of the autozones/napas/checkers and they can do it with their scan tools), if it stays off then the cap was probably just loose, if it comes back on you'll more than likely need a new cap.

Yeah you can do that but I think the thing is here he is ***-U-ME ing that the cel is related to the gas cap light, he don't know. If he had a tuner it would tell him exactly what was wrong, even better than the scanner tools they use at the parts stores.For example, I popped a cel for a 02 sensor the other day and the SC tuner told me which one it was. The scanner tools they use at the parts stores just say 02 sensor bad, not which one. I think he needs to find out what the code is he is throwing and if its related then the first thing I would do is buy a new gas cap. Always try the cheapest first. But if he can find out what the CEL is then it might expalin the problem more.

Don't know what to tell you. The gas cap code went away a couple of starts after I replaced the cap. 2006 Mega Cab. It has not returned. No one cleared the codes.
