Diagnostic Procedure

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Disconnect IVTC solenoid valve 2-pin harness connector. Turn ignition on. Measure voltage between ground and IVTC solenoid valve harness connector terminal No. 1 (Red wire). If battery voltage does not exist, go to next step. If battery voltage exists, go to step  3.
  2. Check the following: See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL.
    • Harness connectors E1 and M1.
    • Harness connectors M33 and F22.
    • Harness continuity between IVTC solenoid valve and ECM relay.
    Repair harness or connectors.
  3. Turn ignition off. Disconnect ECM 116-pin harness connector. For ECM location, see Figure. Check continuity of Orange/Black wire between Bank 1 IVTC solenoid valve harness connector terminal No. 2 and ECM harness connector terminal No. 11, or Pink/Blue wire between Bank 2 IVTC solenoid valve harness connector terminal No. 2 and ECM harness connector terminal No. 10. See Figure and Fig 1 . Also check circuit for short to ground and short to voltage. If problem is found, repair as necessary. After repair, repeat DTC CONFIRMATION TEST . If no problem is found, go to next step.
  4. Measure resistance between IVTC solenoid valve terminals No. 1 and 2 (component side). Resistance should be 7.0-7.7 ohms at 68°F (20°C). Check continuity between ground and IVTC solenoid valve terminals one at a time. Continuity should not exist. If resistance and continuity are as specified, go to next step. If resistance or continuity is not as specified, replace IVTC solenoid valve and retest system. After repair, repeat DTC CONFIRMATION TEST .
  5. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
