DTC Troubleshooting: P0713 (28-4)

DTC P0713: Open in ATF Temperature Sensor Circuit NOTE:

- Record all freeze data and review General Troubleshooting Information before you troubleshoot.
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

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

Does ATF temperature sensor voltage exceed 4.93 V?

YES | - | Go to Step 2 .
NO | - | Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and PCM.■

1. Turn the ignition switch OFF.

1. Disconnect the shift solenoid harness connector.

1. Turn the ignition switch ON (II).

1. Measure the voltage between shift solenoid harness connector terminal No. 6 and body ground.

Is there about 5 V?

YES | - | Go to Step 6 .
NO | - | Go to Step 7 .

1. Measure the voltage between shift solenoid harness connector terminals No. 6 and No. 7.

Is there about 5 V?

YES | - | Check the ATF temperature sensor and shift solenoid harness in the transmission housing. ■
NO | - | Repair open in the wire between PCM connector terminal A23 and the shift solenoid harness connector, then go to Step 8 .

1. Measure the voltage between PCM connector terminal C14 and body ground.

Is there about 5 V?

YES | - | Repair open in the wire between PCM connector terminal C14 and the shift solenoid harness connector, then go to Step 8 .
NO | - | Check for loose or poor connections at PCM connector terminal C14. If the connection 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 .■

1. Clear the DTC with the HDS.

1. Test-drive the vehicle for several minutes in the D position in all five gears.

1. Monitor the OBD status for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the result indicate a pass?

YES | - | The problem has been corrected.■
NO | - | Return to Step 1 and recheck.■
