Variable Induction Check Valve: Testing and Inspection

INSPECTION





1. Disconnect negative (-) terminal cable from battery.

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.





2. Remove V-bank cover. Using a 5 mm hexagon wrench, remove the 2 cap nuts and V-bank cover. Disconnect the Vacuum Switching Valve VSV connector.
3. 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.





4. 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.

5. Inspect VSV operation.





- Check that air flows from pipe E to the filter.





- Apply battery voltage across the terminals.
- Check that air flows from pipe E to pipe F. If operation is not as specified replace the VSV.
