Subaru Problems? Ask a Mechanic for Answers ASAP
Hello, my name is***** code usually means vent solenoid has failed or PCM has failed. Test the resistance of the canister vent solenoid, 25 -30 ohms, if good then use a vacuum pump to see if solenoid holds vacuum and releases it, if not then replace the solenoid. One pin on solenoid should have power with key on then other pin is grounded by PCM. If you ground pin 13 at the PCM this should ground other wire going to solenoid, if not you know it is a wiring problem. If so then you know the PCM has failed. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
There should be a place a vacuum line connects to it, can you send me a picture? Thanks.
I see, you will need to rig something up to cover the part that slides into the canister then put vacuum into that part to see if it holds and releases. Considering resistance is out of spec I would test wire between PCM and solenoid, if good then jsut replace the solenoid/valve. Let me know how it goes, thanks.
That is correct, if you ground pin 13 at PCM this should provide the solenoid ground letting you know wiring is good. Let me know, thanks.
