Fuel Pressure Control Solenoid: Testing and Inspection

COMPONENTS FOR REMOVAL AND INSTALLATION

1. REMOVE VACUUM SWITCHING VALVE (VSV).
2. INSPECT VSV.





- 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.





- 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 the air flows from ports E to G.





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