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 ).

6. Turn the ignition switch ON (II).

7. 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 8.

NO -Go to step 18.

8. Turn the ignition switch OFF.

9. Remove the jumper wire from the ECT sensor 2 2P connector.

10. Turn the ignition switch ON (II).

11. Measure voltage between ECT sensor 2 2P connector terminal No. 1 and body ground.
