Diagnostic Procedures

  1. Perform OBD-II system check. See ON-BOARD DIAGNOSTIC II (OBD-II) SYSTEM CHECK  . After performing OBD-II system check, go to next step.
  2. Turn ignition on. Using scan tool, read and record FAILURE RECORDS data for DTC P0342. Operate vehicle within conditions noted in FAILURE RECORDS data. Using scan tool, monitor specified DTC parameters. If scan tool displays DTC P0342 FAILED THIS IGN, go to next step. If scan tool does not display DTC P0342 FAILED THIS IGN, see DIAGNOSTIC AIDS  .
  3. Using DVOM, backprobe PCM harness connector terminal D11 (Blue wire). See Figure . With sensor connected, crank engine and monitor DVOM. If reading toggles from 0 to 4 volts, go to next step. If reading does not toggle as described, go to step  7 .
  4. Check for poor connection at PCM terminal D11 (Blue wire). If a problem is found, go to next step. If no problem was found, go to step  6 .
  5. Repair poor connection at PCM terminal D11 (Blue wire) as necessary. Retest system.
  6. Replace and reprogram PCM using required equipment. See PROGRAMMING  . Retest system.
  7. Disconnect CMP sensor. Turn ignition on. Using DVOM, measure voltage at CMP sensor harness connector between Blue and Green wires. If voltage is about 5 volts, go to step  12 . If voltage is not as specified, go to next step.
  8. Using DVOM, measure voltage between CMP sensor harness connector Brown wire and ground. If reading is about 5 volts, go to step  10 . If reading is not as specified, go to next step.
  9. Repair open circuit in Brown wire between PCM harness connector terminal C6 and CMP sensor. See Figure and Figure . Retest system.
  10. Measure voltage between battery positive terminal and CMP sensor harness connector Green wire. If reading is about battery voltage, go to step  12 . If reading is not as specified, go to next step.
  11. Repair open circuit in Green wire between PCM harness connector terminal D8 and CMP sensor harness connector. See Figure and Figure . Retest system.
  12. Turn ignition off. Using DVOM, check continuity of Blue wire between PCM harness connector terminal D11 and CMP sensor. If continuity does not exist, go to next step. If continuity exists, go to step  14 .
  13. Repair open circuit in Blue wire between PCM harness connector terminal D11 and CMP sensor. Retest system.
  14. Turn ignition on. Check for short to ground or voltage in Blue wire between PCM harness connector terminal D11 and CMP sensor. If problem is found, repair as necessary. Retest system. If no problem is found, replace CMP sensor.
