Fuel Pressure Control Solenoid: Testing and Inspection

NOTE: When disconnecting the vacuum hose, always make a mark so that it can be reconnected at original position.

1. Disconnect the vacuum hose from the solenoid valve.
2. Disconnect the harness connector.





3. Connect a hand vacuum pump to the nipple.
4. Connect a battery to the solenoid valve and apply a vacuum to check air-tightness.

Battery voltage B nipple Normal condition

Not applied Open Vacuum leaks
