Leak Detection Valve: Description and Operation
CANISTER VENT (CV) SOLENOID

During the EVAP leak check monitor, the CV solenoid seals the EVAP canister from the atmospheric pressure. This allows the EVAP canister purge
valve to obtain the target vacuum in the fuel tank during the EVAP leak check monitor.
