DTC P0711 Transmission Fluid Temperature Sensor "A" Performance


DESCRIPTION

The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance value which is input into the ECM.

DTC No.
DTC Detection Condition
Trouble Area
P0711
(A) 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 19 min. and 8 km (5 mile) or more, ATF temp. is less than 10°C (50°F)
(B) 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 100°C (212°F) or more when engine coolant temperature reaches 60°C (140°F)
Transmission wire (ATF temperature sensor)

MONITOR DESCRIPTION

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.
After running the vehicle for a certain period, the ATF temperature should increase. When the ATF temperature is below 10°C (50°F), the ECM interprets this as a fault, turns on the MIL.
When the ATF temperature is 100°C (212°F) or more and engine coolant temperature reaches 60°C (140°F) after engine cold start, the ECM also determines this as a fault, turns on the MIL, and stores the DTC.

INSPECTION PROCEDURE

УКАЗАНИЕ:
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.
ПРИМЕЧАНИЕ:
In the table below, the value listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether apart is faulty or not.

READ DATA LIST

  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 (IG).

  5. Turn on the tester.

  6. Select the item "Enter / Powertrain / Engine and ECT / Data List".

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

    Tester Display
    		Measurement Item/Range
    		Normal Condition
    		Diagnostic Note
    A/T Oil Temperature 1
    		ATF Temp. Sensor Value/
    min.: -40°C (-40°F)
    max.: 215°C (419°F)
    1. After Stall Test:
      Approx. 80°C (176°F)
    2. Equal to ambient temperature when cold soak
    		If the value is "-40°C (-40°F)" or "215°C (419°F)", ATF temp. sensor circuit is opened or shorted.

    УКАЗАНИЕ:
    When DTC P0712 is output and the intelligent tester output is 150°C (302°F), 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 THO (TH01) and body ground.

    Temperature Displayed
    		Malfunction
    -40°C (-40°F)
    		Open circuit
    150°C (302°F) or more
    		Short circuit
    УКАЗАНИЕ:
    If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second).
    When P0713 is set, P0711 cannot be detected.
    It is not necessary to inspect the circuit when P0711 is set.
1.CHECK OTHER DTCS OUTPUT (IN ADDITION TO DTC P0711)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and push the intelligent tester main switch on.

  1. When you use intelligent tester:
    Select the item "Powertrain / Engine and ECT / DTC / Current or Pending".

  1. Read the DTCs using the intelligent tester.

    Result:

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