Fig. 74: Evaporative Emission (EVAP) Canister Vent Shut Valve Circuit Diagram 

General Description 

The evaporative emission (EVAP) canister vent shut valve is attached to the EVAP canister to control the 
venting of the EVAP canister to atmosphere. 

The EVAP canister vent shut valve is open (open to atmosphere) when the VSV signal is OFF. 

If the return signal is "OFF" when the engine control module (ECM)/powertrain control module (PCM) outputs 
the "ON" signal to the EVAP canister vent shut valve, the ECM/PCM detects a malfunction and a DTC is 
stored.

The return signal is "OFF" for at least 5 seconds when the ECM/PCM outputs the "ON" signal to the EVAP 
canister vent shut valve. 

Confirmation Procedure with the HDS 

Do the EVAP CVS ON in the INSPECTION MENU with the HDS. 

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
ECM/PCM memory. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs. 

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by 
disconnecting the battery.
