DTC P2183: ECT Sensor 2 Range/Performance Problem

NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION )
  • If DTC P0111 is stored at the same time as DTC P2183, troubleshoot DTC P0111 first, then recheck for DTC P2183
  1. Check for poor connections or loose terminals at ECT sensor 1 and ECT sensor 2

    Are the connections and terminals OK? 

    YES  -Go to step 2

    NO  -Repair the connectors or terminals, then go to step  27

  2. Turn the ignition switch to ON (II)
  3. Check for Temporary DTCs or DTCs with the HDS

    Are DTC P1116 and P2183 indicated at the same time? 

    YES  -Go to step  15

    NO  -Go to step 4

  4. Start the engine, and let it idle for 10 minutes
  5. Check ECT SENSOR 2 in the DATA LIST with the HDS

    Is about 108 °F (42 °C) indicated? 

    YES  -Replace ECT sensor 2 (see ECT SENSOR 2 REPLACEMENT ), then go to step  27

    NO  -Go to step 6

  6. Turn the ignition switch to LOCK (0)
  7. Drain the coolant (see COOLANT CHECK ).
  8. Remove ECT sensor 2 (see ECT SENSOR 2 REPLACEMENT )
  9. Allow ECT sensor 2 to cool to ambient temperature
  10. Note the ambient temperature
  11. Connect ECT sensor 2 to its 2P connector, but do not install it
  12. Turn the ignition switch to ON (II)
  13. Note the value of ECT SENSOR 2 quickly in the DATA LIST with the HDS
  14. Compare the value of ECT SENSOR 2 and the ambient temperature

    Does ECT SENSOR 2 differ 5 4°F(3 °C) or more? 

    YES  -Replace ECT sensor 2 (see ECT SENSOR 2 REPLACEMENT ), then go to step  27

    NO  -Intermittent failure, the system is OK at this time Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM

  15. Start the engine, and let it idle for 10 minutes
  16. Check ECT SENSOR 1 in the DATA LIST with the HDS

    Is about 99 °F (37 °C) or less indicated? 

    YES  -Replace ECT sensor 1 (see ECT SENSOR 1 REPLACEMENT ), then go to step  27

    NO  -Go to step 17

  17. Let the engine idle 10 minutes
  18. Check ECT SENSOR 2 in the DATA LIST with the HDS

    Is about 99 °F (37 °C) or less indicated? 

    YES  -Replace ECT sensor 2 (see ECT SENSOR 2 REPLACEMENT ), then go to step  27

    NO  -Go to step 19

  19. Turn the ignition switch to LOCK (0)
  20. Dram the coolant (see COOLANT CHECK )
  21. Remove ECT sensor 1 (see ECT SENSOR 1 REPLACEMENT ) and ECT sensor 2 (see ECT SENSOR 2 REPLACEMENT )
  22. Allow the sensors to cool to ambient temperature
  23. Note the ambient temperature
  24. Connect ECT sensor 1 and ECT sensor 2 to their 2P connectors, but do not install them
  25. Note the value of ECT SENSOR 1 and ECT SENSOR 2 quickly in the DATA LIST with the HDS
  26. Compare the value of ECT SENSOR 1 and the ambient temperature, and the value of ECT SENSOR 2 and the ambient temperature individually

    Does one of the sensors differ more than 5 4°F (3 °C) from the ambient temperature? 

    YES  -Replace the sensor that differed more than 5 4 °F (3 °C) from the ambient temperature, then go to step 27

    NO  -Intermittent failure, the system is OK at this time Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM

  27. Turn the ignition switch to ON (II)
  28. Reset the ECM/PCM with the HDS
  29. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE )
  30. Check for Temporary DTCs or DTCs with the HDS

    Is DTC P2183 indicated? 

    YES  -Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the ECM/PCM, then go to step  1

    NO  -Troubleshooting is complete If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting
