Diagnostic Procedure (3.3L)

WARNING: This page is about a different car, the 2002 Nissan Xterra and 2002 Nissan Frontier. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Loosen and retighten engine ground bolts. See Figure . Disconnect CKP sensor harness connector. See Fig 1 . Disconnect ECM harness connector. See Figure or Figure . Check continuity of Blue wire between CKP sensor harness connector terminal No. 2 and ECM harness connector terminal No. 47. See Figure . 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  3 .
  2. Check the following:
    • Check for poor connection at Gray, 8-pin connector F38 terminal No. 3 (Blue wire). See Figure . Connector F38 is located on right side of engine compartment. See Figure or Figure .
    • Check for open or short between CKP sensor and ECM.

    Repair as necessary.

  3. Reconnect ECM harness connector. Check continuity between engine ground and CKP sensor harness connector terminal No. 1 (Black/White wire). Continuity should exist. Also, check circuit for 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 poor connection at Gray, 8-pin connector F38 terminal No. 7 (Black/White wire). See Figure . Connector F38 is located on right side of engine compartment. See Figure or Figure .
    • Check Gray, 6-pin joint connector No. 4 (connector F34). Continuity should exist between all terminals. Connector F34 is located near ECM. See Figure or Figure .
    • Check for open or short between CKP sensor and ECM.

    Repair as necessary.

  5. Remove CKP sensor. Visually inspect sensor for chipping. Measure resistance between sensor terminals. Resistance should be about 512-632 ohms at 68°F (20°C). Replace sensor if it is chipped or if resistance is not as specified. If sensor is okay, go to next step.
  6. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
