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.
NOTICE:
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.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Powertrain / Engine and ECT / Data List.
(g) According to the display on the Techstream, read the Data List.

Min.: -40°C (-40°F)
Max.: 150°C
(302°F)
After stall test:
Approximately 80°C

Equal to ambient
temperature when
engine cold
If the value is -40°C (-40°F) or 150°C
(302°F), the No. 1 ATF temperature
sensor circuit is open or shorted.
HINT:
When DTC P0712 is output and the Techstream output is 150°C (302°F) or more, there is a short circuit.
When DTC P0713 is output and the Techstream output is -40°C (-40°F), there is an open circuit.
Check the temperature displayed on the tester in order to check if a malfunction exists.

MALFUNCTION
-40°C (-40°F)
Open circuit
150°C (302°F) or more
Short circuit
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately stored (in 0.5
seconds). When P0713 is stored, P0711 cannot be stored.
It is not necessary to inspect the circuit when P0711 is stored.
