DTC P0713: Open in ATF Temperature Sensor Circuit
- 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), and wait for 20 seconds.
- Check the ATF temperature sensor voltage with the HDS in the A/T data list.
Does 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 at 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.
- 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 7.
NO - Go to step 8.
- 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 (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 14.
NO - Repair open in the wire between PCM connector terminal C12 and the ATF temperature sensor connector, then go to step 14.
- 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 connector, then go to step 14.
NO - Go to step 9.
- Connect the ATF temperature sensor connector.
- Update the A/T software in the PCM if it does not have the latest software (see UPDATING THE PCM ), or substitute a known-good PCM (see SUBSTITUTING THE PCM ).
- Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine in P. Run the engine for at least 10 seconds.
- Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu 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 13.
- 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 (see PCM REPLACEMENT ). If any other DTCs were indicated on step 12, go to the INDICATED DTC'S TROUBLESHOOTING .
NO - 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 (see SUBSTITUTING THE PCM ), then recheck. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 11 and recheck.
- Connect the ATF temperature sensor connector.
- Clear the DTC with the HDS.
- Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine in P: Run the engine for at least 10 seconds.
- Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu 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 18.
- 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 17, go to the INDICATED DTC'S TROUBLESHOOTING .
NO - 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 16 and recheck.
