Inspection Procedure

WARNING: This page is about a different variant/trim than selected.

HINT:

According to the DATA LIST displayed by the OBD II scan tool or hand-held 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.

  1. Warm up the engine.
  2. Turn the ignition switch off.
  3. Connect the OBD II scan tool or hand-held tester to the DLC3.
  4. Turn the ignition switch to the ON position.
  5. Push the "ON" button of the OBD II scan tool or the hand-held tester.
  6. When you use hand-held tester:

    Select the item "DIAGNOSIS/ENHANCED OBD I I/DATA LIST".

  7. According to the display on tester, read the "DATA LIST".
NORMAL CONDITION

Item Measurement Item/ Range (display) Normal Condition
AT FLUID TEMP ATF Temp. Sensor Value/ min.: -40°C (-40°F) max.:215°C (419°F) Approx. 80°C (176°F) (After Stall Test)

HINT:

When DTC P0712 is output and OBD II scan tool or hand-held tester output is 150°C (302°F), there is a short circuit.

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

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

MALFUNCTION CHART

Temperature Displayed Malfunction
-40°C (-4CTF) 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 ON ADDITION TO PTC P0711) 
    1. Connect the OBD II scan tool or the hand-held tester to the DLC3.
    2. Turn the ignition switch to the ON position and push the OBD II scan tool or the hand-held tester main switch ON.
    3. When you use hand-held tester:

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

    4. Read the DTCs using the OBD II scan tool or the hand-held 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" is output, perform the troubleshooting for those DTCs first.

    1. B: GO TO RELEVANT DTC CHART (See  DIAGNOSTIC TROUBLE CODE CHART  ) 
    2. A: GO TO NEXT STEP. 
  2. CHECK TRANSAXLE FLUID LEVEL (See  AUTOMATIC TRANSAXLE FLUID  ) 

    OK: Automatic transaxle fluid level is correct. 

    1. NG: ADD FLUID 
    2. OK: REPLACE TRANSMISSION WIRE (See  REPLACEMENT  )
