Canister Purge Solenoid: Testing and Inspection
VACUUM SWITCHING VALVE (VSV) INSPECTION
1. REMOVE VSV
Disconnect the connector and 2 EVAP hoses, and remove the screw and VSV.
2. INSPECT VSV
A. Inspect VSV for open circuit
Using an ohmmeter, measure the resistance between the terminals.
Resistance: At 20°C (68°F): 29 - 33 ohm
If resistance is not as specified. 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 air flows difficulty from port E to port F.
(b) Apply battery positive voltage across the terminals.
