4 Runner SR5 2WD V6-3.4L (5VZ-FE) (1997)
Leak Detection Solenoid: Testing and Inspection
VACUUM SWITCHING VALVE (VSV) FOR VAPOR PRESSURE SENSOR 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
It 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 P, and does not flow from ports E to F.
