POWER STEERING SOLENOID VALVE
Description INFOID:0000000003305950
Power steering solenoid valve controls the power steering oil pressure in the gear housing assembly.
Diagnosis Procedure INFOID:0000000003305951
1.CHECK POWER STEERING SOLENOID VALVE SIGNAL
1. Turn the ignition switch OFF.
2. Check 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 HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CON-
TROL UNIT
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 continuity between power steering control unit harness connector and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace damaged parts.
3.CHECK POWER STEERING SOLENOID VALVE
Check power steering solenoid valve. Refer to STC-8, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 4.
NO >> Replace gear-sub assembly. Refer to ST-24, "
Exploded View".
4.CHECK TERMINALS AND HARNESS CONNECTORS
? Check power steering control unit pin terminals for damage or loose connection with harness connector.
