DTC P0713: Open in ATF Temperature Sensor Circuit

NOTE:
  • Record all freeze data and review General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION  ) before you troubleshoot.
  • This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
  1. Check ATF temperature sensor voltage with the HAS in the A/T data list.

    Does ATF temperature sensor voltage exceed 4.93 V? 

    1. YES  - Go to step 2.
    2. NO  - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and PCM.
  2. Turn the ignition switch OFF.
  3. Disconnect the ATF temperature sensor connector at the transmission end cover.
  4. Turn the ignition switch ON (II).
  5. Measure the voltage between ATF temperature sensor connector terminal No. 2 and body ground.

    Is there about 5 V? 

    1. YES  - Go to step 6.
    2. 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? 

    1. YES  - Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT  ), then go to step  11.
    2. NO  - Repair open in the wire between PCM connector terminal A28 and the ATF temperature sensor connector, then go to step  11.
  7. Turn the ignition switch OFF.
  8. Jump the SCS line with the HAS.
  9. Disconnect PCM connector A (73P).
  10. Check for continuity between PCM connector terminal A3 and ATF temperature sensor connector terminal No. 2.

    Is there continuity? 

    1. YES  - Check for loose or poor connections at PCM connector terminal A3. If the connection is OK, update the PCM if it does not have the latest software, or substitute a known-good PCM (see PCM UPDATING AND SUBSTITUTION FOR TESTING  ), then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.
    2. NO  - Repair open in the wire between PCM connector terminal A3 and the ATF temperature sensor connector, then go to step 11.
  11. Clear the DTC with the HAS.
  12. Test-drive the vehicle for several minutes in the D5 position through all five gears.
  13. Monitor the OBD status for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

    Does the result indicate PASSED? 

    1. YES  - Troubleshooting is complete.
    2. NO  - Return to step  1 and recheck.
