AUTOMATIC TRANSMISSION SYSTEM, Diagnostic DTC:P0711

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

DESCRIPTION

The oil temperature sensor within the valve body detects the oil temperature within the transmission hydraulic control circuit, and inputs into the TCM a signal corresponding to the oil temperature.

DTC No.

DTC Detection Condition


  1. Diagnosis Condition

  2. Malfunction Status

  3. Malfunction Time

  4. Other

 Trouble Area
P0711

  1. Detects that the park/neutral position switch assembly is normal, the shift position sensor is in D, the ATF temperature with ignition switch ON is less than 20°C (68°F) , the present ATF temperature is less than 20°C (68°F) , and the vehicle speed is 40 km/h or more

  2. If any of the following conditions are met:


    1. While diagnostic conditions are satisfied, the variation in oil temperature sensor input voltage is 0.05V or less after the ignition switch is turned to ON

    2. While diagnostic conditions are satisfied, the variation in oil temperature sensor input voltage is 0.05V or less

  3. Continues for 600 sec.

  4. 2-trip detection logic

  • Transmission wire (ATF temperature sensor)

  • Harness and connector

MONITOR DESCRIPTION

This DTC indicates that there is a problem with output from the automatic transmission fluid (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 an opens or shorts in the ATF temperature circuit or a fault of 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) and the variation in oil temperature sensor input voltage is 0.05V or less after running the vehicle for a certain period, the TCM interprets this as a fault, and turns on the MIL.

  1. DATA LIST

    Note


    • Perform the universal trip to clear permanent DTCs Click here.

    • In the table below, the value listed under "Normal Condition" are reference values.

    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 ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch ON.

    5. Turn the GTS on.

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

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

      • After Stall Test;

        Approx. 80°C (176°F)

      • Equal to ambient temperature when cold soak

      Tech Tips

      When DTC P0712 is output and GTS output is -40°C (-40°F), there is a short circuit.

      When DTC P0713 is output and GTS output is 171°C (340°F), there is an open circuit.

      Temperature Displayed Malfunction
      171°C (340°F) Open circuit
      -40°C (-40°F) or more Short circuit

PROCEDURE


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


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch ON and push the GTS main switch ON.

    3. When you use GTS:

      Enter the following menus: Powertrain / ECT / Trouble Codes.

    4. Read the DTCs using the GTS.

      Result
      Display (DTC output) Proceed to
      Only "P0711" is output A
      "P0711" and other DTCs B

      Tech Tips

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