DTC Troubleshooting: P0713 (28)

DTC P0713: Open in ATF Temperature Sensor Circuit

NOTE:

- Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information. How to Troubleshoot A/T Systems

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

1. Check the ATF Temp Sensor voltage with the HDS in the A/T data list.

Does the ATF Temp 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 the PCM.


2. Turn the ignition switch to LOCK (0).

3. Disconnect the ATF temperature sensor connector at the transmission end cover.

4. Turn the ignition switch to ON (II).

5. Measure the voltage between ATF temperature sensor connector terminal No. 2 and body ground.

Is there about 5 V?
YES - Go to step 6.

NO - Go to step 7.






6. Measure the voltage between ATF temperature sensor connector terminals No. 1 and No. 2.

Is there about 5 V?
YES - Replace the ATF temperature sensor, Service and Repair then go to step 16.

NO - Repair open in the wire between PCM connector terminal C16 and the ATF temperature sensor connector, then go to step 16.






7. Turn the ignition switch to LOCK (0).

8. Jump the SCS line with the HDS.

9. Disconnect PCM connector C (49P).

10. Check for continuity between PCM connector terminal C33 and ATF temperature sensor connector terminal No. 2.

Is there continuity?
YES - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM. If the connections are OK, go to step 11.

NO - Repair open in the wire between PCM connector terminal C33 and the ATF temperature sensor, then go to step 16.






11. Connect all connectors.

12. Update the A/T software in the PCM if it does not have the latest software, Service and Repair or substitute a known-good PCM. How to Troubleshoot A/T Systems

13. Start the engine in P, and let it run for at least 20 seconds.

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

Is DTC P0713 indicated?
YES - If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1.

NO - Go to step 15.


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

Does the HDS indicate PASSED?
YES - If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM. Service and Repair If any other DTCs were indicated on step 14, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals at the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM, How to Troubleshoot A/T Systems then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 12 and recheck.


16. Connect the ATF temperature sensor connector.

17. Clear the DTC with the HDS.

18. Start the engine in P, and let it run for at least 20 seconds.

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

Is DTC P0713 indicated?
YES - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to step 1.

NO - Go to step 20.


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

Does the HDS indicate PASSED?
YES - Troubleshooting is complete. If any other DTCs were indicated on step 19, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, return to step 18 and recheck.
