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.

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 / Trouble Codes.

    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.

    NG

    ADJUST FLUID LEVEL Click here

    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
      E6-27 (THO1) or E6-35 (E2) - Body ground Always 10 kΩ or higher

  5. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - TCM)


    1. A01GJ47E05

      Disconnect the E50 transmission wire connector.

    2. Disconnect the E6 TCM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E50-8 (OIL) - E6-27 (THO1) Always Below 1 Ω
      E50-9 (E2) - E6-35 (E2) Always Below 1 Ω
