Diagnostic Procedures

  1. Perform On-Board Diagnostic II (OBD-II) system check. See SELF-DIAGNOSTICS - INTRODUCTION article. Go to next step.
  2. Turn ignition on. Using scan tool, read and record FAILURE RECORDS data for DTC P0341. Operate vehicle within conditions noted in FAILURE RECORDS data. Using scan tool, read specified DTC. If scan tool displays DTC P0341 FAILED THIS IGN, go to next step. If scan tool does not display DTC P0341 FAILED THIS IGN, see DIAGNOSTIC AIDS .
  3. Using DVOM, backprobe PCM connector at CMP signal circuit. With sensor connected, crank engine and monitor voltage. If voltage toggles from 0 to 4 volts, go to next step. If voltage does not toggle as described, go to step  7.
  4. Check for poor connection at PCM connector terminal D11. If a problem is found, go to next step. If no problem is found, go to step  6.
  5. Repair damaged terminal or pin at PCM. Retest system.
  6. Replace and reprogram PCM using required equipment. See PROGRAMMING . Retest system.
  7. Disconnect CMP sensor. Turn ignition on. Measure voltage at CMP sensor harness connector between sensor feed circuit and sensor ground circuit. If reading is about battery voltage, go to step  12. If reading is not as specified, go to next step.
  8. Measure voltage between CMP positive connector at CMP sensor harness connector and ground. If reading is about battery voltage, go to step  10. If reading is not as specified, go to next step.
  9. Repair open between PCM main relay and CMP sensor. Retest system.
  10. Measure voltage between battery positive and CMP ground wire at CMP sensor harness connector. If reading is around battery voltage, go to step  12. If reading is not as specified, go to next step.
  11. Repair open in ground circuit. Retest system.
  12. Turn ignition off. Using DVOM, check continuity of signal wire between CMP sensor and PCM. If continuity does not exist, go to next step. If continuity exists, go to step  14.
  13. Repair open signal wire. Retest system.
  14. Turn ignition on. Check signal wire for short to ground or short to voltage. If problem is found, go to next step. If no problem is found, go to next step.
  15. Repair signal circuit as necessary. Retest system.
  16. Replace CMP sensor. Retest system.
