I had same thing about a month ago, I looked at owners manual and said to insert and remove the plastic filler thing a couple times. It didn't clear when I did that but on the steering wheel I hit the reset button and it went away And hasn't came back since.
Did you make it in to the dealership today, Eboost14? What's the current mileage on your truck?
I got my truck back from the dealership this morning. I was told there was some sort of "evap leak" somewhere. However, I had to much gas in my truck for them to provide a definite diagnoses. So they ended up "blowing out the lines" and resetting the computer. According to them if the error reappears or a check engine light appears there is infact an issue some where. Otherwise they said it is as simple as the easy fill flap was not closing completely. They did point out sometimes using a gas pump which the nozzle is to narrow to open the easy fill cap can trigger some problems....this happened to me prior to the light coming on.
Great help! thank you! this tracks a lot with what my service manger at Ford was trying to explain lol haha.
Ya, Evap leak means the computer is sensing the fuel tank is not holding pressure. Usually always means filler cap is not sealed all the way. With the new EZ fuel just means the flapper probably needs to be cleaned a little.
Or this! Forgot Stant made one for our trucks. Good Call.
