Code P0446 2000 Toyota Camry Description
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 open.
The P0446 code is triggered when an improper voltage signal is sent to Engine Control Module through the EVAP canister vent control valve.
