1. REMOVE VSV.
-
Disconnect the connector and 3 EVAP hoses from the VSV.
-
Remove the bolt and VSV.
2. 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 ohms
-
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.
