Fuel Pressure Control Solenoid: Testing and Inspection

VSV FOR FUEL PRESSURE CONTROL INSPECTION



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

3. INSPECT VSV
A. 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.

B. 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.

C. 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.

4. REINSTALL VSV
- Install the VSV with the screw.
- Connect the 2 vacuum sensing hoses to the VSV.

5. REINSTALL EMISSION CONTROL VALVE SET
6. REINSTALL V-BANK COVER
