Leak Detection Valve: Description and Operation
CANISTER VENT SOLENOID
Typical Canister Vent (CV) Solenoid
During the EVAP Leak Check Monitor, the canister vent (CV) solenoid (Figure 105) 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 EVAP Leak Check Monitor.
