Leak Detector: Description and Operation

CHARCOAL CANISTER SHUTOFF VALVE
The charcoal Canister Shutoff Valve is part of the Evaporative Vacuum Leak Detection (EVLD) system. The charcoal Canister shutoff Valve is mounted on the EVAP Canister. This assembly is located above a splash shield in front of the right rear axleshaft.

The Charcoal Canister Shutoff Valve is actuated by the PCM to isolate the EVAP purge system in order to determine if a leak exists in any of the purge system components.
