|P0446 2008 FORD FUSION code description

The Evaporative System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid valve responds to signals from the Engine Control Module (ECM). When the ECM sends an ON signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.
This solenoid valve is used only for diagnosis, and usually remains opened.
