P0455 - Is the Dealer Lying to Me?
#1282740 - 07/20/06 10:06 PM

I took my 98 2.5L contour to the dealer after seeing the check engine light.

I assumed it might be the gas cap. My wife didn't screw it on all the way and this gas cap has become extremely difficult to put on. I don't know if it is stripped or what but it takes me a good 5-10 minutes to get it on. Its a physical issue.

The dealer got a P0455 code told me the vent valve and i believe solenoid (i might be mistating this) had to be replaced at a cost of $950.

I asked him if a P0455 could be set off by a bad gas cap or a lack of seal there. He said P0455 has nothing to do with it, which contradicts what i've read here. He told me they couldn't even reset the CEL light.

I got home and checked out the gas cap. it was barely on (not my doing though i did tell them to check it). I've ordered a new gas cap and took my car but I'm wondering if i can trust this dealer.

I am also wondering if the thing the gas cap screws into can be replaced in case the new cap still has problems going in.

Thanks. Any help appreciated.

I just had that problem yesterday! I remembered my gas cap did not thread in right, and it must have set the code. I used some Vaseline on the cap and hole threads, after cleaning the dirt out of them first. Then I could tighten the cap properly. I might just get a new cap if it keeps being a pain. (If you Google search P0455, it shows that code is often caused by a loose cap.) The code did not reset itself when I fixed the cap, I had to use my (fairly cheap,at Advance Auto) Actron code scanner to reset the codes. So far, it is fine. The dealer could certainly reset the codes, it would come back if the cap is loose..

A loose gas cap most certainly can cause this code. Follow this link:

Yes, the filler neck can be replaced if necessary (assumig that Ford has not discontinued the part.

I'm also experiencing a "tight" or hard to screw in gas cqp so please let us know if a new cap solves the problem or if you need the filler neck too.

Vaseline , is a cheap solution. I think the cap warps or expands in hot weather. If a new cap solves the problem, I will change mine, too.

We reset CEL codes all day. Pull Fuses 4 and 11 (in the Power Distribution Box next to the battery) for a few minutes. Of course, if the cap is loose, it will come on again after a few drive cycles.

Same thing happened to my kid's car, P0455. The cause was an improperly tightened gas cap.
FYI, you can go to AutoZone and have any codes read and erased for free.

And, welcome to the CEG.

Doesnt undoing the battery also reset the computer? I had a check engine light for a vacuum leak fixed it and had my dad just unplug both battery cables and hasnt come on since? Didnt know about the fuses. Guess that would have been easier. Well, I had to clean the positive battery post anyway. It was corroded.

Yes, it does. But you also lose your preprogrammed radio stations and you have to reset the clock.
