Note: When disconnecting the vacuum hose, mark its position so that the hose can be reconnected in its original position.
1. Disconnect the vacuum hose from the solenoid valve.
2. Disconnect the electrical connector from the solenoid valve.
3. Connect a hand vacuum pump to the nipple (B, Fig. 4.36) of the solenoid valve.
Fig. 4.36. Connecting the hand vacuum pump to the solenoid valve port (B)
4. Check for vacuum leakage from the solenoid valve by applying vacuum and voltage to the solenoid valve connector terminals and disconnecting the voltage.
5. Check the resistance between the contacts of the solenoid valve connector (Fig. 4.37).
