Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** and thanks for your question.
P0446 is indicating a concern with the canister vent solenoid circuit. The solenoid on the firewall is the canister purge solenoid. The canister vent solenoid is located at the rear of the vehicle, it is attached to the fuel filler neck. To access you need to remove the left hand rear wheel well splash shield. I would remove that and inspect the wiring for any damage. If none found then you can replace the vent solenoid. It is possible there is a concern elsewhere in the circuit or powertrain control module. To properly diagnose you would need an advanced scanner that can actuate the solenoid to test for power and ground signal from the PCM.

OK sounds good. Best of luck!
Has to be wiring or PCM concern, as I stated before you need a scanner that can activate the solenoid for circuit testing.

Agreed, but if the wire ohms out then what? How can you test if the ground driver is working?
