P0446 Code

[Dano5]

Sorry for all the post. This is my daughters car and like to get this fixed.

Service engine soon light comes on and P0446. I have replaced the purge valve, vent valve and vapor canister.

Does anybody have an idea what else the issue could be?

Thank in advanced.

The code only points to the vent valve, none of the other parts.
Assuming you used a new valve the other possibilities are all related to the wire harness and PCM
