Diagnostic Procedure (2.4L)

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. 2 (Black/Pink wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short between EVAP-CPVCSV, ECM relay and ECM.
  2. 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, repair as necessary. If problem is not found, go to next step.
  3. If using CONSULT-II, go to next step. If not using CONSULT-II, go to step  5 .
  4. 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  6 . If operation is not as specified, go to next step.
  5. 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.
  6. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
