Along with my 04 H.O CTD I also have a 2002 2500 QC LB 4X4 5.9 gas engine
that was my fathers because he passed away in August. I am getting the same
code. I too changed the gas cap... It still triggers the code. The only way
you can erase it is to unhook the battery or you need a scan tool. Let me
know if you figure out what the problem is.
One thing I did consider was, with the high price of gas my niehbor kid
doesnt have a job but he is always driving around in his truck. I think that
trick from the 70's is back. Stealing gas and forgetting to tighten the gas
cap all the way.
Just a thought.
Suddenly, without warning, Sledneck exclaimed (06-Oct-05 2:22 AM):
I have the same problem, but it's highly unlikely anyone's stealing gas
from my truck. My code changed from this to a different one, which I
don't quite remember but means "it's worse now" (p0455?). I suspect,
since I *never* hear that vaccum sound when I take my new gas cap off,
that the vaccum pump is kaput. Doesn't seem to be a lot of rust on the
- receiver? - but I need to have another look.
My '02 1500 QC set this code. Problem was a split vacuum hose on the
canister. Easy and FREE fix! Only trick was finding the canister. It was
mounted inboard of the drivers side frame rail - under the truck!
