DTC P0447 EVAP CANISTER VENT CONTROL VALVE
Component Description INFOID:0000000004537308
The EVAP canister vent control valve (3) is located on the EVAP
canister (2) and is used to seal the canister vent.
This solenoid valve responds to signals from the 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.
When the vent is closed, under normal purge conditions, the evapo-
rative emission control system is depressurized and allows EVAP
control system diagnoses.
• EVAP control system pressure sensor (1)
