DTC P1446 EVAP CANISTER VENT CONTROL VALVE
The 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 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, Gross Leak, Very Small Leak)" diagnosis.

Do I need to Replace the Vent Control Valve or the Solenoid Valve which send the signal to the Vent Control Valve - to Open or Close. The problem I am having is when I am fulling up at the pump the gas keep shooting out the "Tank" as if the Tank is full when its not.
I really need to know what I need to change, the "Solenoid" which a Part found under the Hood or the Vent Control Valve.
Thanks, your help is very important to me.
