Fuel Pressure Control Solenoid: Testing and Inspection

PROCEDURE





1. Inspect vacuum switching valve for open circuit.
- Using an ohmmeter, check that there is continuity between the terminals.

Resistance (Cold): 37 - 44 ohms

- If there is no continuity, replace the vacuum switching valve.





2. Inspect vacuum switching valve for ground.
- Using an ohmmeter, check that there is no continuity between each terminal and the body.
- If there is continuity, replace the vacuum switching valve.





3. Inspect vacuum switching valve operation.
- Check that air flows from ports E to G.





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