'02 Ford Escape Emission Code?
Hi,
I have a '02 Escape 3.0 L.
The emissions light has been coming on every other day for a couple of weeks with the code of PO 455.
I bought a new Motorcraft gas cap for it, but that didn't fix the problem.
What do I check from here? Thanks! Kevin

Can someone narrow down this problem?
Every 3rd day the gas cap light or emissions light come on.
On one day the gas cap light comes on, put on a new Motorcraft gas cap. cleared light.
On the 3rd day the emission light comes on (PO 455) I checked for possible leaks.(took down the canister tray and checked everything there) cleared code.
It alternates every 3rd day between the two warning lights.
What should I check, other than taking it for a smoke test, first?
If it was either the purge valve, solenoid valve, or check valve, don't they have their on individual trouble codes?
HELP! Thanks, Kevin

A canister vent valve stuck open will cause this problem, but if any of the other named parts have a fault, it would have to be an electrical circuit fault for it to have a fault code that points to the specific part.

The CV valve is usually on or adjacent to the canister.
I have no idea if the o-ring is bad. That's why I told you to take it to a shop with a smoke machine, they will be able to spot the leak very quickly and you won't drive yourself crazy.
