Variable Induction Check Valve: Testing and Inspection

1. REMOVE V-BANK COVER AND EMISSION CONTROL VALVE SET AND HIGH - TENSION CORD COVER
2. REMOVE VSV
- Disconnect the 2 vacuum hoses from the VSV.
- Remove the screw and VSV.





3. INSPECT VSV
- Inspect VSV for open circuit
- Using an ohmmeter. check that there is continuity between each terminal.

Resistance: At 2O°C (68°F): 33 - 39 ohms.

- If there is no continuity, replace the VSV.





- 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.





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





- Check that air flows from pipe E to the filter.
- Apply battery positive voltage across the terminals.
- Check that air flows from pipe E to pipe F. If operation is not as specified, replace the VSV.
4. REINSTALL VSV
- Install the VSV with the screw.
- Connect the 2 vacuum to the VSV.
5. REINSTALL EMISSION CONTROL VALVE SET.
6. REINSTALL HIGH-TENSION CORD COVER.
7. REINSTALL V-BANK COVER.
