DTC Code DTC Detection Condition Trouble Area
P0711

Either condition is met (2-trip detection logic):


  • (a) Certain monitor enabling conditions are met and the ATF temperature is below 20°C (68°F).

  • (b) Certain monitor enabling conditions are met and the ATF temperature is 110°C (230°F) or higher.

  • Transmission wire (ATF temperature sensor)

  • Harness or connector

  • TCM

MONITOR DESCRIPTION

This DTC indicates that there is a problem with output from the ATF temperature 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 TCM determines the ATF temperature and detects open or short circuits in the ATF temperature sensor circuit or faults in the ATF temperature sensor.

After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature is below 20°C (68°F), or 110°C (230°F) or higher after driving the vehicle for a certain period, the TCM interprets this as a fault, illuminates the MIL and stores the DTC.

INSPECTION PROCEDURE

Tech Tips

Using the intelligent tester 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.

Note

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.


  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the intelligent tester on.

  6. Enter the following menus: Powertrain / ECT / Data List.

  7. According to the display on the tester, read the Data List.

    Tester Display Measurement Item/Range Normal Condition Diagnostic Note

    ATF temperature sensor value/

    Min.: -40°C (-40°F)

    Max.: 215°C (419°F)

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

    • While engine cold:

      Equal to ambient temperature

    		 If the value is -40°C (-40°F) or 150°C (302°F), the ATF temperature sensor circuit is open or short-circuited.

    Tech Tips


    • When DTC P0712 is output and the intelligent tester output is 150°C (302°F) or higher, there is a short circuit.

    • When DTC P0713 is output and the intelligent tester output is -40°C (-40°F), there is an open circuit. Check the temperature displayed on the intelligent tester in order to check if a malfunction exists.

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

    Tech Tips

    If a circuit related to the ATF temperature sensor becomes open, P0713 is stored in approximately 0.5 seconds. It is not necessary to inspect the circuit when P0711 is stored.

PROCEDURE


  1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0711 AND P0713)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Powertrain / ECT / DTC.

    5. Read the DTCs using the intelligent tester.

      Result
      Display (DTC output) Proceed to
      Only P0711 is output A
      P0711 and P0713 are output B
      DTCs other than P0711 and P0713 are output C

      Tech Tips

      If any other codes besides P0711 and P0713 are output, perform troubleshooting for those DTCs first.

  2. CHECK TRANSMISSION FLUID LEVEL


    1. Check the transmission fluid level Click here.

      OK
      Automatic transmission fluid level is correct.

    OK

  3. CHECK HARNESS AND TRANSMISSION WIRE (TRANSMISSION WIRE - TCM, TRANSMISSION WIRE (ATF TEMPERATURE SENSOR))


    1. A01GKZME04

      Disconnect the E6 TCM connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      E6-27 (THO1) - E6-35 (E2) ATF temperature 10°C (50°F) 5.8 to 7.1 kΩ
      E6-27 (THO1) - E6-35 (E2) ATF temperature 25°C (77°F) 2.5 to 4.5 kΩ
      E6-27 (THO1) - E6-35 (E2) ATF temperature 110°C (230°F) 231 to 263 Ω

      Tech Tips

      The resistance value for the 25°C (77°F) ATF temperature condition is a reference value.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      E6-27 (THO1) - Body ground Always 10 kΩ or higher
      E6-35 (E2) - Body ground Always 10 kΩ or higher
