DTC 0309 EVAP Canister Vent Control Valve (Open)
NOTE: If both DTC P0440 or P1440 and P1448 are displayed, perform TROUBLE DIAGNOSIS FOR DTC P1448 first.
COMPONENT DESCRIPTION
The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid (the EVAP canister vent control 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 evaporative emission control system is depressurized and allows "EVAP Control System
(Small Leak)" diagnosis.
