Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have a code po446 and CEL up right now. 446 indicates a vent circuit malfunction on the EVAP system. I am trying desperately to track the fault. In the photo you see the black charcoal canister with a green arrow pointing to some sort of blue valve. Its that valve I am interested in. I have disconnected the top and bottom purple and red arrows and hold the line (including the blue thing) in my hand. I am able to blow each way through this line. That confuses me as I wonder now why it is in the line in the first place if I can blow each way. No electrical connection to the blue thing. I would have thought I could only blow one way. Does anyone know what its called and what its there for? Is it a good one or a bad one. I hope its a bad one and then my problems will be solved.

POST 3 / ORIGINAL POSTEROriginal post

sorry I disconnected the purple and BLUE not red arrows to get the pipe in my hands. BTW I have replaced the pink thing about 4 months ago and the gas cap.

Try posting your question on Renntech. Someone there may know.

Unfortunately (or fortunately) I don't have much personal experience with this part of the evap system. Agree that renntech is a better place for this kind of deep diagnostic questions.

POST 6Original post

P0446: EVAP Canister Shutoff Valve (Function) � Below Limit Function: The task of the shutoff valve is to seal the purge air line to the EVAP canister during the fuel tank leak test. Purge air line blocked or the flow resistance of air through the charcol canister is too high.
