Diagnostic Procedure

WARNING: This page is about a different car, the 2005 Nissan 350Z. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect intake valve timing control solenoid valve harness connector.

    3. Turn ignition switch ON.
    4. Check voltage between intake valve timing control solenoid valve terminal 2 and ground with CONSULT-II or tester.
      • Voltage: Battery voltage 

    OK or NG

    • OK: GO TO  3.
    • NG: GO TO 2.

  2. DETECT MALFUNCTIONING PART 

    Check the following.

    • Harness connectors E12, F3
    • Harness connectors F18, F201 (Bank 1)
    • Harness for open or short between intake valve timing control solenoid valve and IPDM E/R
      • : Repair open circuit or short to ground or short to power in harness or connectors.
  3. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check harness continuity between ECM terminal 11 (bank 1) or 10 (bank 2) and intake valve timing control solenoid valve terminal 1. Refer to WIRING DIAGRAM .
      • Continuity should exist. 
    4. Also check harness for short to ground and short to power.

    OK or NG

    • OK: GO TO  5.
    • NG: GO TO 4.
  4. DETECT MALFUNCTIONING PART 

    Check the following.

    • Harness connectors F18, F201 (Bank 1)
    • Harness for open and short between ECM and intake valve timing control solenoid valve
      • : Repair open circuit or short to ground or short to power in harness or connectors.
  5. CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE 

    Refer to "COMPONENT INSPECTION ".

    OK or NG

    • OK: GO TO 6.
    • NG: Replace intake valve timing control solenoid valve.
  6. CHECK INTERMITTENT INCIDENT 

    Refer to "TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT ".

    For wiring diagram, Refer to WIRING DIAGRAM  for CKP sensor (POS), WIRING DIAGRAM  and BANK 2  for CMP sensor (PHASE).
