I really need an answer to this question with photo.
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. I have the same question on renntech but no replies in 2 weeks. I hope one of you 996 guys can help me out. I am smoke testing right now and find no vacuum leaks anywhere in the system.
CAN SOMEONE FROM PELICAN PARTS ANSWER MY QUESTION AS Ii AM USING ONE OF THEIR PHOTOS TO DISPLAY THE BLUE DEVICE.

The description on PP associated with that picture refers to it as a "one way check valve", so it does seem strange that you can blow through it both ways.
I really need a good guy to remove his vent line with the blue valve in it and blow through it both ways. To remove it simply finger and thumb squeeze top and bottom connectors. If you are in there, it will take literally 2 minutes. Thanks.
