One of the posters here said he laughed at a dealer who mentioned a loose gas cap. I am here to tell you that on OBD II emissions systems (which your truck has), the gas cap is an integral part of the emissions control. If you run the truck while fueling up (or even have the ignition in the run position) or don't tighten that gas cap real good, you WILL get a check engine light. I would first make sure you are doing the above and if that does not work, go get a new gas cap. Any salvage yard with late model vehicles will practically give them away; if you ever dropped yours on cement or something it could have a hairline crack in it, that would be all you need to get the error code. Let the boards know the outcome...we are curious.
