DTC Code DTC Name
P0711 Transmission Fluid Temperature Sensor "A" Performance

DESCRIPTION

DTC Code DTC Detection Condition Trouble Area
P0711

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


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

    2. After normal driving for over 21 min. and 9 km (6 miles) or more, ATF temperature is less than 20°C (68°F)

 No. 1 ATF temperature sensor

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 ECM determines the ATF temperature and detects opens or shorts in the ATF temperature circuit or a fault 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) after running the vehicle for a certain period, the ECM interprets this as a fault, and illuminates the MIL.

INSPECTION PROCEDURE

Tech Tips

Using the intelligent tester's Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.


  1. Warm up the engine.

  2. Turn the ignition switch OFF.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the ignition switch ON and push the tester main switch ON.

  5. Enter the following menus: Powertrain / Engine and ECT / Data List.

  6. Follow the instructions on the tester and read the Data List.

Tester Display Measurement Item/Range Normal Condition Diagnostic Note

No. 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 during cold soak

 If value is -40°C (-40°F) or 215°C (419°F), No. 1 ATF temperature sensor circuit is opened or short circuited

CAUTION:

In the table above, 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.

Tech Tips


  • When DTC P0712 is output and the intelligent tester output is 150°C (302°F) or more, 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.

    Measure the resistance between terminal THO1 (OT) and the 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 is set in approximately 0.5 seconds.

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

PROCEDURE


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


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch ON and push the intelligent tester main switch ON.

    3. Enter the following menus: Powertrain / Engine and ECT / DTC / Current or Pending.

    4. Read the DTCs using the intelligent tester.

      Tech Tips

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