10 minutes? You da man!! Takes an old fat guy like me that long to open the box it came in.

People like you are one of the reason's for Amazon's "frustration-free packaging".

Ha you’re right. I got mine from Amazon and the box was so beat up they re-taped it to death. Thankfully us old guys still carry pocket knives.

Which part fixed the problem?

 

[FINALTOUCHFRI]

ACDelco 214-2341 GM Original Equipment Vapor Canister Vent Valve, it took longer to take the spare down then it did to replace the valve. Super quick. Disconnected battery after the repair and code cleared. Yepa!!!

make sure you give it a couple days to "self check", the code could come back in a day or two if that wasn't for the sure the problem, when it is colder in the morning and you first start the truck and drive it a mile or or two is when the code could resurface, what I am saying is since you cleared the code it may not detect a vacuum leak again until it does the vacuum process again, engine temp has to be below a certain threshold @swathdiver I think has it noted because he had a small vacuum leak also. keep your fingers crossed, I would say if the code does not come back by the 3rd day then your good to go.

Yep, P0442, no leak between vent and purge, comes on after 16th or 18th ignition cycle, usually overnight after running those tests. Gotta buy a smoke machine, eventually, other things are taking priority to this annoyance.
