Inspection Procedure

HINT:

Using the Techstream 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 value listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether apart is faulty or not.
  1. READ DATA LIST 
  1. Warm up the engine.
  2. Turn the ignition switch off.
  3. Connect the Techstream to the DLC3.
  4. Turn the ignition switch to ON.
  5. Turn on the Techstream.
  6. Select the item "Powertrain / Engine and ECT / Data List".
  7. According to the display on the Techstream, read the "Data List".
ITEM/RANGE REFERENCE CHART

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)
  • After Stall Test: Approx. 80°C(176°F)
  • 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.

HINT:

When DTC P0712 is output and the Techstream output is 150°C (302°F), there is a short circuit.

When DTC P0713 is output and the Techstream output is -40°C (-40°F), there is an open circuit.

Measure the resistance between terminal THO (TH01) and body ground.

TEMPERATURE SPECIFICATION

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

HINT:

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 Techstream to the DLC3.
    2. Turn the ignition switch to ON and the Techstream main switch on.
    3. Select the item "Powertrain / Engine and ECT / Trouble Codes".
    4. Read the DTCs using the Techstream.

    Result 

    RESULT REFERENCE

    Result Proceed to
    P0711 A
    P0711 and other DTCs B

    HINT:

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

    B: Go to DTC CHART  (See DIAGNOSTIC TROUBLE CODE CHART )

    A: Go to Next Step 

  2. CHECK TRANSMISSION FLUID LEVEL 

    OK: Automatic transmission fluid level is correct  .

    NG: ADD FLUID 

    OK: REPLACE TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)  (See REMOVAL )
