Diagnostic Procedure (I35)

WARNING: This page is about a different car, the 2002 Nissan Maxima and 2002 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Disconnect appropriate IVT control solenoid valve harness connector. See ENGINE CONTROL HARNESS  under CONNECTOR IDENTIFICATION. Turn ignition on. Measure voltage between ground and IVT control solenoid valve harness connector terminal No. 2 (Red/Yellow wire on bank No. 1; Red wire on bank No. 2). If battery voltage exists, go to step  3 . If battery voltage does not exist, go to next step.
  2. Check the following:
    • Check for poor connection at Black, 8-pin connector F18 terminal No. 4 (Red wire). See Fig 1 . Connector F18 is located on left side of engine compartment. See Figure .
    • Check for open or short between ECM relay and IVT control solenoid valve.
    • On bank No. 1 only, check for poor connection at Green 8-pin connector F56 terminal No. 4 (Red wire). See Fig 1 . Connector F56 is located on top front of engine. See Figure .

    Repair as necessary.

  3. Turn ignition off. Disconnect ECM harness connector. See Figure . For bank No. 1, check continuity between IVT control solenoid valve harness connector terminal No. 1 (Red wire) and ECM harness connector terminal No. 9 (Blue/White wire). See Fig 2 . For bank No. 2, check continuity of Green wire between IVT control solenoid valve harness connector terminal No. 1 and ECM harness connector terminal No. 8. Continuity should exist. Also, check circuit for short to ground and short to voltage. If problem is found, go to next step. If problem is not found, go to step  5 .
  4. Check the following:
    • Check for open or short between ECM and IVT control solenoid valve.
    • On bank No. 1 only, check for poor connection at Green 8-pin connector F56 terminal No. 7 (Blue/White wire). See Fig 1 . Connector F56 is located on top front of engine. See Figure .

    Repair as necessary.

  5. Measure resistance between IVT control solenoid valve terminals. Resistance should be 7.0-7.5 ohms at 68°F (20°C). Also, check continuity between ground and each IVT control solenoid valve terminal. Continuity should not exist. If resistance and continuity are as specified, go to next step. If resistance or continuity is not as specified, replace IVT control solenoid valve.
  6. Check CKP sensor. See DTC P0335: CRANKSHAFT POSITION SENSOR (POS) CIRCUIT  . If CKP sensor is okay, go to next step. If CKP sensor is not okay, replace CKP sensor.
  7. Check CMP sensor. See DTC P0340: CAMSHAFT POSITION SENSOR CIRCUIT - BANK 1 OR DTC P0345: CAMSHAFT POSITION SENSOR CIRCUIT - BANK 2  . If CMP sensor is okay, go to next step. If CMP sensor is not okay, replace CMP sensor.
  8. Visually check for chipped signal plate at rear of appropriate intake camshaft. If problem is found, replace camshaft. If problem is not found, go to next step.
  9. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
