Honda Element. Manual - part 689

2. Check ECT SENSOR 2 in the DATA LIST with the HDS. 

Is about 356°F (180°C) or more, or 0.08 V or less indicated?  

YES -Go to step 3. 

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

3. Turn the ignition switch OFF.  

4. Disconnect the ECT sensor 2 2P connector.  

5. Turn the ignition switch ON (II).  

6. Check ECT SENSOR 2 in the DATA LIST with the HDS. 

Is about 356°F (180°C) or more, or 0.08 V or less indicated?  

YES -Go to step 7. 

NO -Go to step 11. 

7. Turn the ignition switch OFF.  

8. Jump the SCS line with the HDS.  

9. Disconnect ECM/PCM connector E (31P).  

10. Check for continuity between ECT sensor 2 2P connector terminal No. 1 and body ground.

11. Turn the ignition switch OFF.  

12. Replace ECT sensor 2 (see ECT SENSOR 1 REPLACEMENT ).  

13. Reconnect all connectors.  

14. Turn the ignition switch ON (II).  

15. Reset the ECM/PCM with the HDS.  

16. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).  

17. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P2184 indicated?  

YES -Check for poor connections or loose terminals at 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 DTCS TROUBLESHOOTING. 

18. Reconnect all connectors.  

19. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or 

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).  

20. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P2184 indicated?  

YES -Check for poor connections or loose terminals at ECT sensor 2 and the ECM/PCM. If the 
ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then recheck. 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 Temporary DTCs or 
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING. 

DTC P2185: ECT SENSOR 2 CIRCUIT HIGH VOLTAGE 

1. Turn the ignition switch ON (II).  

2. Check ECT SENSOR 2 in the DATA LIST with the HDS. 

Is about -40°F (-40°C) or less, or 4.92 V or more indicated?  

YES -Go to step 3. 

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot, and 
review the general troubleshooting information (see GENERAL 
TROUBLESHOOTING INFORMATION ).
