NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot, and review GENERAL TROUBLESHOOTING INFORMATION .
  • Information marked with an asterisk (*1) applies to '11-12 models (M/T).
  • Information marked with an asterisk (*2) applies to '11-12 models (A/T).
  1. Turn the ignition switch to ON (II).
  2. Clear the DTC with the HDS
  3. Start the engine, and let it idle for 20 seconds
  4. Check for Pending or Confirmed DTCs with the HDS.

    Is DTC P0201, P0202, P0203, or P0204 indicated? 

    YES:  Go to step  5.

    NO:  Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the injectors and the ECM/PCM.

  5. Turn the ignition switch to LOCK (0).
  6. Disconnect the injector 2P connector from problem cylinder.
  7. At the injector side, measure the resistance between injector 2P connector terminals No. 1 and No. 2.

    Is there 10-13 Ω? 

    YES:  Go to step 8

    NO:  Go to step  18

  8. Turn the ignition switch to ON (II).
  9. Measure the voltage between injector 2P connector terminal No. 1 and body ground.

    Is there battery voltage? 

    YES:  Go to step 10

    NO:  Repair an open in the wire between the injector and PGM-FI main relay 1, then go to step  19.

    Is there continuity? 

    YES:  Repair a short in the wire between the ECM/PCM and the injector, then go to step  19.

    NO:  Go to step  24

  15. Jump the SCS line with the HDS.
  16. Disconnect ECM/PCM connector C (49P).
  17. Check for continuity between appropriate injector 2P connector terminal No. 2 and the appropriate ECM/PCM connector terminal of the problem cylinder (see table below).

    Is there continuity? 

    YES:  Go to step  25

    NO:  Repair an open in the wire between the ECM/PCM and the injector, then go to step  19.

  18. Replace the problem injector (see INJECTOR REPLACEMENT ).
  19. Reconnect all connectors.
  20. Turn the ignition switch to ON (II).
  21. Reset the ECM/PCM with the HDS.
  22. Do ECM/PCM IDLE LEARN PROCEDURE .
  23. Start the engine, and let it idle for 20 seconds.
  24. Check for Pending or Confirmed DTCs with the HDS.

    Is DTC P0201, P0202, P0203, or P0204 indicated? 

    YES:  Check for poor connections or loose terminals at the injector and the ECM/PCM, then go to step  1.

    NO:  Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.

  25. Reconnect all connectors.
  26. Update the ECM/PCM if it does not have the latest software, or substitute a knowngood ECM/PCM.
  27. Start the engine, and let it idle for 20 seconds.
  28. Check for Pending or Confirmed DTCs with the HDS.

    Is DTC P0201, P0202, P0203, or P0204 indicated? 

    YES:  Check for poor connections or loose terminals at the the injectors, and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  27. If the ECM/PCM was substituted, go to step  1.

    NO:  If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT  ). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
