DTC P2183: ECT Sensor 2 Range/Performance Problem Honda Fit GE

Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review 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 connections or terminals, then go to step 27 .
2. Turn the ignition switch to ON (II).
3. Check for Pending or Confirmed 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 126°F (52°C) indicated? YES: Replace ECT sensor 2 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ), 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»(ref-320432-S30222595332009071400000) ).
8. Remove ECT sensor 2 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ).
9. Allow ECT sensor 2 to cool to the 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. Quickly 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 from ambient temperature? YES: Replace ECT sensor 2 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ), 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 97°F (36°C) or less indicated? YES: Replace ECT sensor 1 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ), 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 126°F (52°C) or less indicated? YES Replace ECT sensor 2 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ), then go to step 27 . NO Go to step 19 .
19. Turn the ignition switch to LOCK (0).
20. Drain the coolant (see «COOLANT CHECK»(ref-320432-S30222595332009071400000) ).
21. Remove ECT sensor 1 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ) and ECT sensor 2 (see «ECT SENSOR 1 REPLACEMENT»(ref-320426-S22783962312009071400000) ).
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. Quickly 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 «ECM/PCM IDLE LEARN PROCEDURE»(ref-320447-S03803966382009071400000) .
30. Check for Pending or Confirmed 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 Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
