DTC P0711: Problem in ATF Temperature Sensor Circuit

NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, 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
  1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and wait for 20 seconds
  2. Check the ATF Temperature with the HDS in the A/T Data List

    Does the ATF Temperature indicate -4°F (-20°C) or below? 

    YES  -Go to step 3

    NO  -Go to step  5

  3. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on)
  4. Check the ATF Temperature with the HDS in the A/T Date List

    Does the ATF Temperature remain -4°F (-20°C) or below? 

    YES  -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step  8

    NO  -Intermittent failure, the system is OK at this time If there is an abnormal temperature rise in the ATF temperature sensor, go to step  16

  5. Check the ATF Temperature with the HDS in the A/T Data List

    Does the ATF Temperature exceed 230°F (110°C)? 

    YES  -Go to step 6

    NO  -Intermittent failure, the system is OK at this time

  6. Leave the engine off until the Engine Coolant Temperature reads 122°F (50°C) with the HDS in the A/T Date List
  7. Check the ATF Temperature with the HDS in the A/T Data List

    Does the ATF Temperature remain 230°F (110°C) or higher? 

    YES  -Replace the ATF temperature sensor (see ATF TEMPERATURE SENSOR REPLACEMENT ), then go to step 8

    NO  -Intermittent failure, the system is OK at this time If there is an abnormal decrease in temperature of the ATF temperature sensor, go to step  16

  8. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  9. Clear the DTC with the HDS
  10. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on)
  11. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, and allow the engine to coolant cool to the outside air temperature (the Engine Coolant Temperature reads the same as the outside air temperature)
  12. With SH-AWD Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely

    13. Without SH-AWD Block the rear wheels and raise the front of the vehicle, make sure it is securely supported, and allow the front vehicles to rotate freely, or raise the vehicle on a lift

  13. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and wait for 20 seconds, then start the engine Warm the engine up to normal operating temperature (the radiator fan comes, on) Start off in D, accelerate with the throttle opened at least 4 degrees, and run the vehicle at speeds over 19 mph (30 km/h) for at least 5 minutes O, test-drive the vehicle for at least 20 seconds while the ATF temperature reads -4°F to 230°F (-20°C to 110°C) by monitoring with the HDS Slow down, and stop the wheels
  14. Check for Pending or Confirmed DTCs with the HDS

    15. Is DTC P0711 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 15

  15. Monitor the OBD status for P0711 in the DTCs MENU with the HDS

    16. Does the HDS indicate PASSED? 

    YES  -Troubleshooting is complete If any other Pending or Confirmed DTCs were indicated in step 14, go to the indicated DTC's troubleshooting

    NO  -If the HDS indicates FAILED, 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, go to step  10

  16. 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 )
  17. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode Start the engine, and warm the engine up to normal operating temperature (the radiator fan comes on)
  18. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, and allow the engine to coolant cool to the outside air temperature (the Engine Coolant Temperature reads the same as the outside air temperature)
  19. With SH-AWD Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely

    20. Without SH-AWD Block the rear wheels and raise the front of the vehicle, make sure it is securely supported, and allow the front vehicles to rotate freely, or raise the vehicle on a lift

  20. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and wait for 20 seconds, then start the engine Warm the engine up to normal operating temperature (the radiator fan comes on) Start off in D, accelerate with the throttle opened at least 4 degrees, and run the vehicle at speeds over 19 mph (30 km/h) for at least 5 minutes Or test-drive the vehicle for at least 20 seconds while the ATF temperature reads -4°F to 230°F (-20°C to 110°C) by monitoring with the HDS Slowdown, and stop the wheels
  21. Check for Pending or Confirmed DTCs with the HDS

    Is DTC P0711 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  15 If the PCM was substituted, go to step  1

    NO  -Go to step 22

  22. Monitor the OBD status for P0711 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 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 If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE ECM/PCM ), then go to step  17 If the PCM was substituted, go to step  1 If the HDS indicates NOT COMPLETED, go to step  17
