Leak Detection Solenoid: Testing and Inspection

VACUUM SWITCHING VALVE (VSV) FOR VAPOR PRESSURE SENSOR INSPECTION

1. REMOVE LH FRONT FENDER LINER





2. REMOVE VSV
(a) Disconnect the VSV connector.
(b) Disconnect the 3 EVAP hoses from the VSV.
(c) Remove the screw and VSV.
3. INSPECT VSV





A. 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.





B. 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.
C. Inspect VSV Operation





(a) Check that the air flows from port E to G.





(b) Apply battery voltage across the terminals.
(c) Check that the air flows from port E to F.
If operation is not as specified, replace the VSV.
4. REINSTALL VSV
5. REINSTALL LH FRONT FENDER LINER
