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.
PROCEDURE
1.
CHECK DTC OUTPUT (IN ADDITION TO DTC P0711)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs using the Techstream.
Result
RESULT
PROCEED TO
Only P0711 is output
A
P0711 and other DTCs are output
B
HINT:
If any other codes besides P0711 are output, perform troubleshooting for those DTCs first.

MONITOR DESCRIPTION
The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the
resistance, the ECM determines the ATF temperature and detects an open or short in the ATF temperature sensor
DTC.
