P0711 Transmission Fluid Temperature Sensor "A" Performance

One of the following conditions (A), (B) or (C) is met:

(A) Both (a) and (b) are detected: (2-trip detection logic)


  • (a) Intake air and engine coolant temperatures are more than 15°C (59°F) at engine start

  • (b) After normal driving for over 10 min. and 0.7 km (0.4 mile) or more, ATF temperature is less than 20°C (68°F)

(B) Both (a) and (b) are detected: (2-trip detection logic)


  • (a) Intake air and engine coolant temperatures are more than -10°C (14°F) at engine start

  • (b) After normal driving for over 15 min. and 50 sec. and 1 km (0.6 mile) or more, ATF temperature is less than 20°C (68°F)

(C) Both (a) and (b) are detected: (2-trip detection logic)


  • (a) Engine coolant temperature is less than 35°C (95°F) at engine start

  • (b) ATF temperature is 110°C (230°F) or more when engine coolant temperature reaches 60°C (140°F)

MONITOR DESCRIPTION

This DTC indicates that there is a problem with output from the automatic transmission fluid (ATF) temperature sensor (TFT sensor) and that the sensor itself is defective. The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects an opens or shorts in the ATF temperature circuit or a malfunction of the ATF temperature sensor.

After driving the vehicle for a certain amount of time, the ATF temperature should increase. If the ATF temperature is below 20°C (68°F) after driving the vehicle for a certain amount of time, the ECM interprets this as a malfunction and illuminates, and turns on the MIL.

CAUTION / NOTICE / HINT

Note


  • Perform registration and/or initialization when parts related to the automatic transmission are replaced.

  • If DTCs P0711 and P2610 are output simultaneously, confirm that the ATF temperature is as specified in "Normal Condition" using the GTS first. When the ATF temperature is as specified in "Normal Condition", perform troubleshooting for DTC P2610.

  1. DATA LIST

    Tech Tips

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.


    1. Warm up the engine.

    2. Turn the engine switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the GTS on.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.

    7. According to the display on the GTS, read the "Data List".


      Powertrain > Engine > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      A/T Oil Temperature 1 ATF temperature sensor value

      Min.: -40°C (-40°F)

      Max.: 215°C (419°F)

      • After stall test: Approximately 80°C (176°F)

      • Equal to ambient temperature when engine cold

      		 If the value is -40°C (-40°F) or 215°C (419°F), the ATF temperature sensor circuit is open or shorted.

      Powertrain > Engine > Data List
      Tester Display
      A/T Oil Temperature 1

      Tech Tips

      When DTC P0712 is output and the data list displays 150°C (302°F) or more, there is a short circuit.

      When DTC P0713 is output and the data list displays -40°C (-40°F), there is an open circuit.

      Measure the resistance between terminal OIL and body ground.

      Temperature Displayed Malfunction
      -40°C (-40°F) Open circuit
      150 °C (302°F) or more Short circuit

      Tech Tips

      If a circuit related to the ATF temperature sensor becomes open, P0713 will be stored in approximately 0.5 seconds. When P0713 is stored, P0711 cannot be detected.

      It is not necessary to inspect the circuit when P0711 is output.

PROCEDURE


  1. CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.


      Powertrain > Engine > Trouble Codes

    4. Read the DTCs using the GTS.

      Only DTC P0711 is output A
      P0711 and other DTCs are output B

      Tech Tips

      If any DTCs other than P0711 are output, perform troubleshooting for those DTCs first.
