Inspection Procedure
Perform the universal trip to clear permanent DTCs. Refer to DTC CHECK / CLEAR [09/2014 - ] .
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.
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
- Warm up the engine.
- Turn the ignition switch off.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine and ECT / Data List.
- According to the display on the Techstream, read the Data List.ECM
Tester Display Measurement Item/Range Normal Condition Diagnostic Note A/T Oil Temperature 1 ATF temperature sensor value/
Min.: -40°C (-40°F)
Max.: 215°C (419°F)- After stall speed test: Approximately 80°C (176°F)
- While engine is cold:
Equal to ambient temperature
If value is -40°C (-40°F) or 150°C (302°F), ATF temperature sensor circuit is open or short circuited HINT:
When DTC P0712 is output and the Techstream indicates 150°C (302°F) or more, there is a short circuit.
When DTC P0713 is output and the Techstream indicates -40°C (-40°F), there is an open circuit.
Measure the resistance between terminal THO1 (OT) and body ground.
Temperature Displayed Malfunction -40°C (-40°F) Open circuit 150°C (302°F) or more Short circuit HINT:
If the circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 seconds). When P0713 is set, P0711 cannot be detected.
It is not necessary to inspect the circuit when P0711 is set.
