DTC P0713: Open in ATF Temperature Sensor Circuit

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General 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 transmission.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
Check the ATF Temp Sensor (V) with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) exceed 4.93 V?

YES - Go to step 3.

NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the ATF temperature sensor and the PCM.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
Disconnect the ATF temperature sensor connector.
Connect ATF temperature sensor connector terminal No. 2 to body ground with a jumper wire.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
Check the ATF Temp Sensor (V) with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) drop to 0.07 V or less?

YES - Go to step 8.

NO - Go to step 13.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
Remove the jumper wire.
Connect ATF temperature sensor connector terminals No. 1 and No. 2 with a jumper wire.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
Check the ATF Temp Sensor (V) with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) remain 0.07 V or less?

YES - Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 17.

NO - Repair an open in the wire between PCM connector terminal C16 and the ATF temperature sensor connector terminal No. 1, then go to step 17.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
Jump the SCS line with the HDS.
Disconnect PCM connector C (49P).
Check for continuity between PCM connector terminal C33 and ATF temperature sensor connector terminal No. 2.

Is there continuity?

YES - Check for poor connections or loose terminals between the ATF temperature sensor and the PCM. If the connections are OK, go to step 23.

NO - Repair an open in the wire between PCM connector terminal C33 and ATF temperature sensor connector terminal No. 2, then go to step 17.
Reconnect all connectors.
Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
Clear the DTC with the HDS.
Start the engine in P, and wait for at least 20 seconds.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0713 indicated?

YES - Check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1.

NO - Go to step 22.
Monitor the OBD STATUS for P0713 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?

YES - Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 21, go to the indicated DTC'S TROUBLESHOOTING .

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 20.
Reconnect all connectors.
Update the PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ).
Start the engine in P, and wait for at least 20 seconds.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0713 indicated?

YES - Check for poor connections or loose terminals between the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 25. If the PCM was substituted, go to step 1.

NO - Go to step 27.
Monitor the OBD STATUS for P0713 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 Pending or Confirmed DTCs were indicated in step 26, go to the indicated DTC'S TROUBLESHOOTING .

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ) then go to step 25. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 25.
