Code P 0456 is described as "Leak has been dectected in the evaporative
system." The gas cap has been removed and reinstalled seventeen times or
more over a three thousand mile period without the check engine light and
code P0456 clearing.
Is there a way to prove the gas filler cap is at fault without replacing the
2002 Dakota, 3.9, auto, quad and if Mr. Red Neck still reads this ng the
color of the truck is Pat. Blue
Yes but a new cap would be cheaper than having a shop test it. If the
cap isn't the problem then you have a leaking hose somewhere. Check all
hoses from the tank to the charcoal canister and from there to the
engine compartment. On top of the canister is a plastic hose manifold.
That could be cracked too.
I agree with miles. Change the gas cap. and to clear the check engine
light, unhook the battery for for 'bout a minute. If it comes back after
that then there is definitely a leak in your lines somewhere. Maybe
replace the lines just so you know that there isn't any leaks. Good luck
Is that Binghamton, NY? Just curious, my brother lives there. Would be
pretty funny if he was looking for a Dodge and I could say "A guy told me
Miller is pretty good."
'Course, my brother never listens to me anyway, but still...;>)
Small world - though Chenango Forks sound like it ought to be out west
somewhere with cowboys and such...
Of course, we have a Hell (as well as a Paradise) here in Michigan, so I
probably shouldn't pick on other people's place names. ;>)
