Or, you need a new fuel fill cap. Those things have a valve inside that prevents fuel vapors from venting to the atmosphere. The valve can fail. The smog checking stations here in Arizona attach the fuel cap to a tester when you bring the truck in for its annual check and if it doesn't pass, you have to get a new one.

Actually, I have. But I thought from his post that he had the older, screw-on style. I'm really not seeing any obvious way to do anything with the new, EZ-Fill cap, or whatever they call it. The door wouldn't trigger the warning, would it?

Well duh! *headslap* I should learn to pay more attention to details (and I used to teach programming!)
OK, there should be no problem if the door on the body side is open or closed, it's just a cover.
Inside, what used to be a fuel cap has a push-down "flap" in the center - that's the best way I can describe it. And, I suppose the flap could be not sealing properly.
I'd suggest taking the funnel that's supplied for adding fuel from a can to the tank and inserting it, then withdrawing it to see if that fixes the problem by resetting the flap. It's not exactly a "flap", and I don't know exactly how it works, but I can't push it open with my finger. Inserting the funnel opens it easily.

Checking other forums, there's actually a TSB on this. What you are suggesting is only one of several possibilities.
