Inspection Procedure

HINT:

According to the DATA LIST displayed by the OBD II scan tool or intelligent tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor 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 intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
    4. Turn the ignition switch to the ON position.
    5. Turn on the tester.
    6. Select the item "DIAGNOSIS / OBD/MOBD / ECT / DATA LIST".
    7. According to the display on the tester, read the "DATA LIST".
      DATA LIST

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      AT OIL TEMPI 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 OBD II scan tool or intelligent tester output is 150°C (302°F), there is a short circuit.

      When DTC P0713 is output and OBD II scan tool or intelligent tester output is -40°C (-40°F), there is an open circuit.

      Measure the resistance between terminal THO1 (THO) and body ground.

      TEMPERATURE DISPLAYED MALFUNCTION

      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 OBD II scan tool or the intelligent tester to the DLC3.
    2. Turn the ignition switch to the ON position and push the OBD II scan tool or the intelligent tester main switch ON.
    3. When you use intelligent tester:

      Select the item "DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES".

    4. Read the DTCs using the OBD II scan tool or the intelligent tester.

      Result 

      RESULT CHART

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

      HINT:

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

    B: GO TO GO TO  DTC 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)
