COMPONENTS FOR REMOVAL AND INSTALLATION

VACUUM SWITCHING VALVE (VSV) FOR FUEL PRESSURE CONTROL
1. REMOVE VSV.




2. INSPECT VSV.
- 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.




- 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 pipe G.




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

3. REINSTALL VSV.
