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 (see GENERAL TROUBLESHOOTING INFORMATION ).
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
Some wire colors vary according to the model year, and are indicated with an asterisk as follows:
- *1: '09-11 models

- *2: '12 model

Check the ATF temperature sensor voltage with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) 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 between the ATF temperature sensor and the PCM.
Turn the ignition switch to LOCK (0).
Disconnect the ATF temperature sensor connector at the transmission end cover.
Connect ATF temperature sensor connector terminal No. 2 to body ground with a jumper wire.

Turn the ignition switch to ON (II).
Check the ATF temperature sensor voltage with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) drop to 0.07 V or below?

YES -Go to step 7.

NO -Go to step 12.
Turn the ignition switch to LOCK (0).
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).
Check the ATF temperature sensor voltage with the HDS in the A/T Data List.
Does the ATF Temp Sensor (V) remain 0.07 V or below?

YES -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 22.

NO -Repair open in the wire between PCM connector terminal C16 and the ATF temperature sensor connector terminal No. 1, then go to step 22.
Turn the ignition switch to LOCK (0).
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 and loose terminals between the ATF temperature sensor and the PCM. If the connections are OK, go to step 16.

NO -Repair open in the wire between PCM connector terminal C33 and the ATF temperature sensor, then go to step 21.
Reconnect all connectors.
Update the A/T software in the PCM if it does not have the latest software (see PCM UPDATE ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
With the shift lever in P, turn the ignition switch to ON (II), and wait for at least 20 seconds. Then start the engine, and wait for at least 10 seconds.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0713 indicated?

YES -If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, go to step 1.

NO -Go to step 20.
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 PCM REPLACEMENT ). If any other Pending or Confirmed 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 between the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 18.
Connect PCM connector C (49P).
Connect the ATF temperature sensor connector.
Clear the DTC with the HDS.
With the shift lever in P, turn the ignition switch to ON (II), and wait for at least 20 seconds. Then start the engine, and wait for at least 10 seconds.
Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0713 indicated?

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

NO -Go to step 26.
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 on step 25, go to the indicated DTC's troubleshooting.

NO -If the HDS indicates FAILED, check for poor connections and loose terminals between the ATF temperature sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 24.
