Fuel Pressure Control Solenoid: Testing and Inspection

INSPECTION





1. Disconnect negative (-) terminal cable from battery.

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.

2. Remove V-bank cover. Using a 5 mm hexagon wrench, remove the 2 cap nuts and V-bank cover.





3. Remove emission control valve set.
4. Remove Fuel Pressure Control Vacuum Switching Valve (VSV)
- Disconnect the 2 vacuum sensing hoses from the Fuel Pressure VSV.
- Remove the screw and Fuel Pressure VSV.



5. Inspect Fuel Pressure 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 Fuel Pressure VSV.





6. Inspect Fuel Pressure VSV for ground.

- Using an ohmmeter, check that there is no continuity between each terminal and the body.
- If there is continuity, replace the Fuel Pressure VSV.
7. Inspect Fuel Pressure 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 Fuel Pressure VSV.
8. Reinstall Fuel Pressure VSV.
- Install the Fuel Pressure VSV with the screw.
9. Reinstall emission control valve set.
- Connect the 2 vacuum sensing hoses to the Fuel Pressure VSV.
10. Reinstall V-bank cover. Using a 5 mm hexagon wrench. install the V-bank cover with the 2 cap nuts.

NOTE: When positioning the V-bank cover, push on the cover until a "click" is felt.

11. Reconnect Negative (-) Terminal Cable To Battery.
