Hello to the group ,would appreciate any thoughts and ideas. The check engine stays lit .the truck is running ok. Took truck to ford dealer to be checked out.Dealer said it needs filler neck replaced. estimated cost is 500.dollars. This neck is leading to gas tank and according to the dealer is deteriorating. thanks hlb
The dealer could be right. Might be the filler neck. I bet your error code had to do with the PURGE circurt.
I'd buy a new gas cap first, it might be all that's wrong.
Other reasons for the code are:
Fuel filling while engine is running. Loose or bad fuel cap. Overfilling the fuel tank, some fuel may get into the PURGE circurt and screw things up.
Those are the common reasons for the error code.
Before letting the dealer do the work, check the web for any recalls or service bulletins on the filler neck.
I don't trust dealers, they will screw you at any opportunity.
