Nissan Maxima Service and Repair Manual: Power steering solenoid valve

Description

Power steering solenoid valve controls the power steering oil pressure in the gear housing assembly.

Diagnosis Procedure

1.CHECK POWER STEERING SOLENOID VALVE SIGNAL

Nissan Maxima. CHECK POWER STEERING SOLENOID VALVE SIGNAL

  1. Start engine.
  2. Check voltage between power steering control unit connector
    M59 terminal 1 and ground

2.CHECK HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CONTROL UNIT FOR OPEN

Nissan Maxima. CHECK HARNESS BETWEEN POWER STEERING SOLENOID VALVE AND POWER STEERING CONTROL UNIT FOR OPEN

  1. Turn ignition switch OFF.
  2. Disconnect power steering solenoid valve connector.
  3. Disconnect power steering control unit connector.
  4. Check continuity between power steering solenoid valve connector
    E14 (A) terminals 1, 2 and power steering control unit
    connector M59 (B) terminal 1, 5.
