DTC P0710 TRANSMISSION FLUID TEMPERATURE
SENSOR ”A” CIRCUIT
DTC P0712 TRANSMISSION FLUID TEMPERATURE
SENSOR ”A” CIRCUIT LOW INPUT
DTC P0713 TRANSMISSION FLUID TEMPERATURE
SENSOR ”A” CIRCUIT HIGH INPUT
CIRCUIT DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance
value which is input into the ECM.
The ECM applies a voltage to the temperature sensor through ECM terminal THO.
The sensor resistance changes with the transmission fluid temperature. As the temperature becomes high-
er, the sensor resistance decreases.
One terminal of the sensor is grounded so that the sensor resistance decreases and the voltage goes down
as the temperature becomes higher.
The ECM calculates the fluid temperature based on the voltage signal.

MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 Ω
*1 or more than 156 kΩ*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will
turn on the MIL and store the DTC.
*1: 150C (302F) or more is indicated regardless of the actual ATF temperature.
*2: –40C (–40F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the Intelligent Tester II display.

INSPECTION PROCEDURE
HINT:
Using the Intelligent Tester II Data List allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor 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 Intelligent Tester II to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item ”Enter / Power train / Engine and ECT / Data List”.
(g) Follow the instructions on the tester and read the Data List.

HINT:
When DTC P0712 is output and Intelligent Tester II output is 150C (302F) or more, there is a short circuit.
When DTC P0713 is output and Intelligent Tester II output is –40C (–40F), there is an open circuit.
Measure the resistance between terminal THO (OT) and body ground.

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.
