Leak Detection Solenoid: Testing and Inspection

VSV INSPECTION 

1. REMOVE VSV

(a) Disconnect the connector, wire clamp and 3 EVAP hoses from the VSV.
(b) Remove the bolt and VSV.

2. INSPECT VSV FOR OPEN CIRCUIT

Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 20°C (68°F): 37 - 44 ohm 

If there is no continuity, replace the VSV.

3. INSPECT VSV FOR GROUND

Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the VSV.

4. INSPECT VSV OPERATION

(a) Check that air flows from ports E to G, and does not flow from ports E to F.
(b) Apply battery voltage across the terminals.
