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. Disconnect EVAP-CPVCSV harness connector. See Figure . Turn ignition on. Measure voltage between ground and EVAP-CPVCSV harness connector terminal No. 1 (Black/Pink wire). 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 White, 24-pin connector M81 terminal No. 13 (Black/Pink wire). See Figure . Connector M81 is located behind right side of instrument panel. See Figure or Figure .
    • Check for poor connection at Super Multiple Junction (SMJ) connector M65 terminal 11A (Black/Pink wire). See Figure . SMJ connector M65 is located under right side of instrument panel. See Figure or Figure .
    • Check for open or short between EVAP-CPVCSV and ECM relay.

    Repair as necessary.

  3. Turn ignition off. Disconnect ECM harness connector. See Figure or Figure . Check continuity of Red/Yellow wire between EVAP-CPVCSV harness connector terminal No. 1 and ECM harness connector terminal No. 5. 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  5 .
  4. Check the following:
    • Check for poor connection at White, 24-pin connector M81 terminal No. 8 (Red/Yellow wire). See Figure . Connector M81 is located behind right side of instrument panel. See Figure .
    • Check for poor connection at Super Multiple Junction (SMJ) connector M65 terminal 9A (Red/Yellow wire). See Figure . SMJ connector M65 is located under right side of instrument panel. See Figure or Figure .
    • Check for open or short between EVAP-CPVCSV and ECM.

    Repair as necessary.

  5. If using CONSULT-II, go to next step. If not using CONSULT-II, go to step  7 .
  6. Reconnect all harness connectors. Start engine. Perform PURG VOL CONT/V in ACTIVE TEST mode with CONSULT-II. Engine speed should vary according to valve opening. If operation is as specified, go to step  8 . If operation is not as specified, go to next step.
  7. Remove EVAP-CPVCSV. Using jumper wires, apply battery voltage between EVAP-CPVCSV terminals. See Figure . Check for airflow between ports "A" and "B". Air should flow. Remove jumper wires. Air should not flow. If operation is as specified, go to next step. If operation is not as specified, replace EVAP-CPVCSV.
  8. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
