Well I got this code last week, and since I'm still under warranty I figured I'd have the dealership take care of it so I don't have to pay for the parts. They checked it out while I was getting my airbag recall done and I have to go back next week for them to replace the canister/vent valve. If I were doing it myself I'd probably just buy the valve you listed but since they're paying I'll let them replace everything.
