Diagnostic Procedures

WARNING: This page is about a different car, the 2000 Isuzu Hombre. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform On-Board Diagnostic II (OBD-II) System Check. See SELF-DIAGNOSTICS - INTRODUCTION article. Retrieve and record FREEZE FRAME and/or FAIL RECORDS data for each DTC set. Go to next step.
  2. Turn engine on and allow it to idle. Retrieve and record FREEZE FRAME and FAILED RECORDS data for DTC P0340. Continue to idle engine for one minute. Observe FREEZE FRAME, LAST TEST FAILED DTC. If DTC P0340 FAILED is not displayed, go to step  8. If DTC P0340 FAILED is displayed, turn engine off. Restart engine. If MIL does not remain on, go to step  8. If MIL remains on, go to next step.
  3. Turn ignition on, with engine off. Disconnect CMP sensor harness connector. Connect a test light between engine ground and CMP sensor ignition feed circuit (Pink wire) at harness connector. If test light comes on, go to next step. If test light does not come on, go to step  9.
  4. Connect test light between CMP sensor ground circuit (Pink/Black wire) and CMP ignition feed circuit (Pink wire). If test light comes on, go to next step. If test light does not come on, go to step  11.
  5. Turn ignition off. Install Gray jumpers from Connector Test Kit (J35616-A) between CMP sensor and CMP sensor harness connector. Using a DVOM, check voltage on CMP sensor signal circuit (Brown/White wire). If voltage is 5-7 volts, go to step  15. If voltage is not 5-7 volts, go to next step.
    NOTE: CMP sensor signal circuit may also be referred to as the CMP sensor 1x signal circuit.
  6. Check CMP sensor harness connector signal circuit (Brown/White wire) for open. If open is found, go to step  13. If circuit is okay, go to next step.
  7. Check CMP sensor harness connector signal circuit (Brown/White wire) for short to voltage or ground. Repair as necessary. If short is not found, go to step  12. If short is found, go to step  13.
  8. DTC P0340 is intermittent. If any additional DTCs are set, diagnose affected DTCs. If no additional DTCs are set, see DIAGNOSTIC AIDS .
  9. Check for open in CMP sensor ignition feed circuit (Pink wire). If open is found, go to step  13. If circuit is okay, go to next step.
  10. Repair short to ground in CMP sensor ignition feed circuit (Pink wire). After repair, go to step  17.
  11. Repair open in CMP sensor ground circuit (Pink/Black wire). After repair, go to step  17.
  12. Check for faulty connection at CMP sensor. If faulty connection is found, go to next step. If connection is okay, go to step  14.
  13. Repair circuit(s) and/or connection(s) as necessary. After repairs, go to step  17.
  14. Replace CMP sensor. After replacing sensor, go to step  17.
  15. Check for faulty connection at VCM. If faulty connection is found, go to step  13. If connection is okay, go to next step.
  16. Replace VCM. Program replacement VCM. See PROGRAMMING . After replacing VCM, go to next step.
  17. Using scan tool, select DTC, CLEAR INFO function. Start engine and allow it to reach operating temperature. Using scan tool, select DTC, SPECIFIC function and enter DTC P0340. Operate vehicle within conditions required to set DTC. If scan tool displays RAN AND PASSED, go to next step. If scan tool does not display RAN AND PASSED, return to step  2.
  18. Using scan tool, select Read and Record INFO, REVIEW INFO function. If any undiagnosed DTCs are displayed, diagnose affected DTCs. If no DTCs are displayed, system is okay.
