Crown Victoria V8-4.6L VIN W (2000)
Leak Detection Valve: Description and Operation
Canister Vent Solenoid
Typical Canister Vent (CV) Solenoid
During the Enhanced EVAP System test monitor, the Canister Vent (CV) solenoid seals the EVAP canister from atmospheric pressure. This allows the
EVAP canister purge valve to obtain the target vacuum in the fuel tank during the monitor run.
The canister vent solenoid:
^
is normally open.
^
seals the EVAP system for the inspection and maintenance (I/M 240) test and OBD II leak and pressure tests.
^
is mounted to the evaporative emission canister.
^
is repaired as a separate item.
