Leak Detection Valve: Description and Operation
EVAP Canister Shut-Off Valve (Certain Markets Only)
The EVAP canister shut-off valve is used to close the connection between the EVAP canister/fuel tank system and fresh air (atmospheric pressure) when
leak diagnostics are carried out on the cars with the evaporative emission (EVAP) system.
The valve is an electro-magnetic valve which is powered from the system relay. When the valve needs to be closed, it is grounded internally in the engine
control module (ECM). The valve is open when in the rest position (open-circuit).
The engine control module (ECM) can diagnose the valve. The valve can be activated using VADIS.
The valve is next to the EVAP canister on cars with leak diagnostics for the evaporative emission (EVAP) system.
