Leak Detection Solenoid: Testing and Inspection

INSPECTION 

1. REMOVE VSV

(a) Disconnect the 3 EVAP hoses from the VSV.
(b) Remove the screw and VSV.

2. INSPECT VSV FOR OPEN CIRCUIT

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

Resistance: 33 - 39 ohms at 20°C (68°F)  

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 the air flows from ports E to P.
(b) Apply battery positive voltage across the terminals.

(c) Check that the air flows from ports E to F.
