Truck runs fine, except it's fuel usage could be better. Check engine
light throws code P0455.
Ok, so I know P0455 means a large evaporative emissions leak. It used
to be p0422 or whatever the small leak message is, but has changed.
I changed the gas cap, code comes back. I still never get that little
vacuum noise when I remove the gas cap. The receiver top seems to be
plastic, what's underneath looks a little rusted. Could it be the cause
of the error? is this a "user replaceable" part?
In looking up the code, it said to check the gas cap, or "Inspect the
EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise
or smell fuel), repair if necessary"
The inspection part sounds like something I could do myself, if only I
knew what I should be inspecting. Is it possible for someone to tell me
what I should be looking at/for? Or should I just take it to a mechanic
and let them have at it? What sort of costs am I looking at to repair this?
I was originally gonna wait till we got back to the US to get this fixed
(we're already starting to pack!), but now it looks like we're going to
Remoteville in a country with no Chryslers, much less Dodge.
Any help appreciated. Guess I'd better go find myself a Haynes manual :)
