Check Fuel Cap light
Hey guys new issue that I did not find in the search archives.
The Check fuel cap light is now on and will not go off. Removed fuel cap and reinstalled to make sure it was ok, and it was.
Tried to reset it by cycling the key on-off three times did not help. Thinking about disconnecting battery for a few hours to see it will reset.
Not a safety issue but a bit annoying.
Thanks for any and all help.

He-he that's good! appreciate the reply. If it happens again I'll get another cap.
Did notice that the seal around the rubber gasket was not uniform so not surprised.
You guys have good new years!

I would start by resetting it yourself, just unhook the negative battery cable for at least two minutes. This should clear any codes you have then if the lights show back up then you might have a sensor/cap problem.

Auto-reset?
Just had the "Check Fuel Cap" illuminate on my '02. Replaced the old cap with a new one on the advice of a Pepboys mechanic but no change. When I went back to him he apologised and said he should have mentioned that it would take a few days and maybe 50 miles or so before the computer logic re-set the light. It's been a few days and about 100 miles and the light is still on! I'll try dis-connecting the battery but if that doesn't work then it's into the shop. The handbook says that the "Check Engine" light will be triggered if you drive around with the "Check Fuel Light" on for any length of time. I know this isn't a solution but it may just add to the knowledge-base. I'll update my results.

The light sets when it detects a large leak in the Evaporative Emissions system.. the control the detect a fuel vapor leak. If you have a hose off on the system or a bad seal, it can set that light. It's not ALWAYS the gas cap (just 90% of the time)
good luck

Just had mine come on our 2003 Explorer, so we bought a new cap for it and I reset the gas cap light with a scan tool. Hopefully that will fix the problem. Anything else that can cause it to come on that's common other then the gas cap?
