Testing and Inspection

VSV INSPECTION



1. REMOVE V-BANK COVER AND EMISSION CONTROL VALVE SET AND HIGH-TENSION CORD COVER.

2. REMOVE VSV.
- Remove the filter.
- Disconnect the 2 vacuum hoses from the VSV.
- Remove the screw and VSV.

3. INSPECT VSV FOR OPEN CIRCUIT.



- Using an ohmmeter, check that there is continuity between the terminals.

Resistance At 20°C (68°F): 33 - 39 Ohms

- 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 port E to port G.



- Apply battery positive voltage across the terminals.
- Check that air flows from port E to the filter.
- If operation is not as specified, replace the VSV.

6. REINSTALL VSV.
- Install the VSV with the screw.
- Connect the 2 vacuum hoses to the VSV.
- Install the filter.

7. REINSTALL EMISSION CONTROL VALVE SET.
8. REINSTALL HIGH-TENSION CORD COVER.
9. REINSTALL V-BANK COVER.
