P0446?

[Vaginaterian]

I have the code and a reader so I know what I'm up against. I just need to now where the canister and vent valve assy is located so I can clean out the works. Should this plan of attack be ok?

If no one knows the answer to your question, this information would be in a factory service manual set for your specific year/model vehicle (4 book set you can get from your dealer).

 

That's what I use my books for a LOT, is where is the darn thing located!

Thanks for your help, I have the same issue with my 2002 Tahoe. I expect this is the cure.
