Check GAS CAP error message on 2003 Ford Expedition

Nov 09, 2006 1 Replies

We've been to the dealer TWICE and paid them over $300 to "guess" at this problem. Anyone have any insight or solutions as to why the "Check Gas Cap" message keeps reappering? Hell yes we've checked and replaced the gas cap as well as smoke tested for tank leakage, and allegedly tested the sensor and the computer.



Any help apprecitated.

Why are you paying for this? Emissions warranty should cover any emissions related issue.
