I think one of two things are going on with this code.Either pieces of charcoal break free from canister and float in system causing a blockage in the VSV,or the VSV goes electrically open,or the VSV works but cannot seal properly internally...Most of the time the VSV sticks,But before you replace the VSV inspect the hoese very carefully for floating pieces of charcoal..If there are any small pieces,you will need to replace the charcoal assy.

its a major bummer that none of these links and pics work any more. just got a quote from the stealer. the VSV is $60 and the canister is $400! i guess i will try replacing just the valve and hope that works. any write ups with working pix would be appreciated. thanks.

You are going to need to remove the canister and replace the VSV with the canister on the bench,should be held onto the canister with either a 10mm or phillips screw(gonna be tight,use good screwdriver and body weigh to limit cam-out)..Just mark where all the hoses go and it should go smoothly...
BTW.. can you post the VSV part# for the canister(2001-2002)?

goat, that diagram will help a lot. ive read a few post about the canister being located somewhere under the truck on some model years. can you point me to the general area where your canister is? is your VSV below the canister as documented by others? thanks for the help!
