POWER STEERING SOLENOID VALVE





Component Function Check
1.CHECK POWER STEERING SOLENOID VALVE OPERATION
Check changes in steering force from a halt condition to high-speed driving.
Is the inspection result normal?
YES - INSPECTION END
NO - Check the power steering solenoid valve. SEE Diagnosis Procedure.




Diagnosis Procedure
1.CHECK POWER STEERING SOLENOID VALVE SIGNAL
Check the voltage between power steering control unit harness connector and ground.





Is the inspection result normal?
YES - GO TO 4.
NO - GO TO 2.
2.CHECK POWER STEERING SOLENOID VALVE CIRCUIT
1. Turn the ignition switch OFF.
2. Disconnect power steering solenoid valve harness connector.
3. Disconnect power steering control unit harness connector.
4. Check the continuity between power steering solenoid valve harness connector and the power steering control unit harness connector.





5. Check the continuity between power steering control unit harness connector and ground.





Is the inspection result normal?
YES - GO TO 3.
NO - Repair or replace error-detected parts.
3.CHECK POWER STEERING SOLENOID VALVE
Check the power steering solenoid valve. SEE Component Inspection.
Is the inspection result normal?
YES - GO TO 4.
NO - Power steering solenoid valve is malfunctioning. Replace gear-sub assembly. Removal And Installation, Removal And Installation (AWD).
4.CHECK TERMINALS AND HARNESS CONNECTORS
- Check the power steering control unit pin terminals for damage or loose connection with harness connector.
- Check the power steering solenoid valve pin terminals for damage or loose connection with harness connector.
Is the inspection result normal?
YES - INSPECTION END
NO - Repair or replace error-detected parts.




Component Inspection
1.CHECK POWER STEERING SOLENOID VALVE
