Fail Safe Solenoid Valve: Testing and Inspection

Inhibitor Solenoid Test

1. Remove the air cleaner Service and Repair.

2. Disconnect the solenoid wire harness 8P connector (A).





3. Measure the inhibitor solenoid resistance between solenoid wire harness 8P connector (B) terminal No. 5 and body ground.





4. If the resistance is out of standard, check for open or short in the solenoid wire harness. If the wire is OK, replace the inhibitor solenoid Inhibitor Solenoid Replacement.

5. Connect a jumper wire from the battery positive terminal to solenoid wire harness 8P connector terminal No. 5, and connect another jumper wire from the battery negative terminal to body ground.
A clicking sound should be heard.

6. If no clicking sound is heard, replace the inhibitor solenoid Inhibitor Solenoid Replacement.
