DTC Troubleshooting: P0712 (28-3)

DTC P0712:  Short in ATF Temperature Sensor Circuit


NOTE:

1.Check ATF temperature sensor voltage with the Honda PGM Tester or HDS in the A/T data list.

Is ATF temperature sensor voltage 0.16 V or less?


YES - Go to 2.


NO - Intermittent failure, the system is OK at this time.n


2.Disconnect the shift solenoid harness connector at the shift solenoid valve cover.

3.Check ATF temperature sensor voltage with the Honda PGM Tester or HDS.

Is ATF temperature sensor voltage 0.16 V or less?


YES - Go to 4.


NO - Faulty  ATF temperature sensor, replace it. After replacing the sensor, go to 8, and check that the repair has been completed.n


4.Turn the ignition switch OFF.

5.Jump the SCS line with the Honda PGM Tester or HDS.

6.Disconnect PCM connector C (22P).

7.Check for continuity between the No. 6 terminal of the shift solenoid harness connector and body ground.

Is there continuity?


YES - Repair short to ground in the wire between PCM connector terminal C14 and the shift solenoid harness connector.n


NO - Check for a short to ground in the shift solenoid harness wire in the transmission. If the wire is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n


8.Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS.

9.Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.

10.Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0712.

Did the result pass?


YES - The problem has been corrected.n


NO - Return to step 1 and recheck.n
