Honda Civic. Manual — part 192

1. Turn the ignition switch to ON (II).
2. Check the ATF TEMP SENSOR voltage in the DATA LIST with the HDS.

Is the ATF TEMP SENSOR voltage 0.07 V or less?

YES -Go to step 3.

NO -Intermittent failure, the system is OK at this time. Check for an
intermittent short to body ground in the ATFT wire between the ATF
temperature sensor and the PCM.

3. Turn the ignition switch to LOCK (0).
4. Disconnect the shift solenoid harness connector.
5. Turn the ignition switch to ON (II).
6. Check the ATF TEMP SENSOR voltage in the DATA LIST with the HDS.

Is the ATF TEMP SENSOR voltage 0.07 V or less?

YES -Go to step 7.

NO -Replace the ATF temperature sensor (see ATF TEMPERATURE
SENSOR TEST/REPLACEMENT ), then go to step 12.

7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector B (44P).

10. Check for continuity between shift solenoid harness connector terminal No. 6

and body ground.

Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).

This code is caused by an electrical circuit problem and
cannot be caused by a mechanical problem in the

Is there continuity?

YES -Repair short to body ground in the wire between PCM connector
terminal B27 and shift solenoid harness connector terminal No. 6, then go to
step 12.

NO -Go to step 11.

11. Check for continuity between shift solenoid harness connector terminal No. 6

and body ground.

YES -Replace the ATF temperature sensor (see ATF TEMPERATURE
SENSOR TEST/REPLACEMENT ), then go to step 12.

NO -Go to step 18.

12. Reconnect all connectors.
13. Turn the ignition switch to ON (II).
14. Clear the DTC with the HDS.
15. Start the engine with the shift lever in P, and wait for at least 20 seconds.
16. Check for DTCs with the HDS.

Is DTC P0712 indicated?

YES -Check for intermittent short to body ground in the wire between the ATF
temperature sensor and the PCM, then go to step 1.

NO -Go to step 17.

17. Monitor the OBD STATUS for P0712 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step
16, go to the INDICATED DTC'S TROUBLESHOOTING.

NO -If the HDS indicates FAILED, check for intermittent short to body ground
in the wire between the ATF temperature sensor and the PCM, then go to step
1. If the HDS indicates NOT COMPLETED, go to step 15.

18. Update the PCM if it does not have the latest software (see UPDATING THE

PCM ), or substitute a known-good PCM (see SUBSTITUTING THE
PCM ).

19. Start the engine with the shift lever in P, and wait for at least 20 seconds.
20. Check for DTCs with the HDS.

Is DTC P0712 indicated?

YES -Check for intermittent short to body ground in the wire between the ATF
temperature sensor and the PCM. If the PCM was updated, substitute a known-
good PCM (see SUBSTITUTING THE PCM ), then go to step 19. If the
PCM was substituted, go to step 1.

NO -Go to step 21.

21. Monitor the OBD STATUS for P0712 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was
substituted, replace the original PCM (see ECM/PCM REPLACEMENT ). If
any other DTCs were indicated in step 20, go to the INDICATED DTC'S
TROUBLESHOOTING.

NO -If the HDS indicates FAILED, check for intermittent short to body ground
in the wire between the ATF temperature sensor and the PCM. If the PCM was
updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ),
then go to step 19. If the PCM was substituted, go to step 1. If the HDS
indicates NOT COMPLETED, go to step 19.

DTC P0713: Open in ATF Temperature Sensor Circuit

1. Turn the ignition switch to ON (II).
2. Check the ATF TEMP SENSOR voltage in the DATA LIST with the HDS.

Does the ATF TEMP SENSOR voltage exceed 4.93 V?

NOTE:

Before you troubleshoot, record all freeze data and any
on-board snapshot with the HDS, and review General
Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).
