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.

Turn the ignition switch to ON (II).
Check the ATF TEMP SENSOR voltage in the DATA LIST with the HDS.
Does the ATF TEMP SENSOR voltage 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).
Disconnect the ATF temperature sensor connector at the transmission end cover.
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 TEMP SENSOR voltage in the DATA LIST with the HDS.
Does the ATF TEMP SENSOR voltage exceed 4.93 V?

YES -Go to step 8.

NO -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 18.
Turn the ignition switch to LOCK (0).
Remove the jumper wire from the ATF temperature sensor connector.
Turn the ignition switch to ON (II).
Measure the voltage between ATF temperature sensor connector terminal No. 2 and body ground.

Is there about 5 V?

YES -Go to step 12.

NO -Go to step 17.
Turn the ignition switch to LOCK (0).
Jump the SCS line with the HDS.
Disconnect PCM connector C (22P).
Connect ATF temperature sensor connector terminal No. 1 and body ground with a jumper wire.

Is there continuity?

YES -Go to step 24.

NO -Repair open in the wire between PCM connector terminal C12 and the ATF temperature sensor, then go to step 18.
Measure the voltage between PCM connector terminal C3 and body ground.

Is there about 5 V?

YES -Repair open in the wire between PCM connector terminal C3 and the ATF temperature sensor, then go to step 18.

NO -Go to step 24.
Reconnect all connectors.
Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Start the engine in P, and let it run for at least 20 seconds.
Check for 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 23.
Monitor the OBD STATUS for P0713 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step 22, go to the INDICATED DTC'S TROUBLESHOOTING .

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to step 1. If the screen indicates NOT COMPLETED, go to step 21.
Update the PCM if it does not have the latest software (see UPDATING THE PCM ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
Start the engine in P, and let it run for at least 20 seconds.
Check for 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 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 screen 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 DTCs were indicated in step 26, go to the INDICATED DTC'S TROUBLESHOOTING .

NO -If the screen 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 PCM ), then go to step 25. If the PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, go to step 25.
