DTC P0711TRANSMISSION FLUID TEMPERATURE
SENSOR ”A” PERFORMANCE
CIRCUIT DESCRIPTION
The ATF (Automatic Transmission Fluid) temperature sensor converts the fluid temperature into a resistance
value which is input into the ECM.
DTC No.DTC Detection ConditionTrouble Area
P0711
(A) Both (a) and (b) are detected: (2−trip detection logic)
(a) Intake air and engine coolant temperatures are more than
−10˚C (14_F) at engine start
(b) After normal driving for over 19 min. and 8 km (5 mile) or
more, ATF temp. is less than 10˚C (50_F)
(B) When engine coolant temp. is less than 35˚C (95_F) at
engine start, the ATF temp. is 110˚C (230_F) or more after
17 min. of engine start (2−trip detection logic).

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 opens or shorts in the ATF temperature
circuit or a fault of the ATF temperature sensor.
After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature
is below 10_C (50_F) after running the vehicle for a certain period, the ECM interprets this as a fault, and
turns on the MIL.
When the ATF temperature is 110_C (230_F) or more after 17 minutes of engine cold start, the ECM also
determines this as a fault, turns on the MIL, and stores the DTC.

INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the 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.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the hand −held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the ”ON” button of the hand −held tester.
(f) Select the item ”DIAGNOSIS / OBD/MOBD / DATA LIST”.
(g) According to the display on tester, read the ”DATA LIST”.

When DTC P0712 is output and hand −held tester output is 150 _C (302 _F), there is a short circuit.
When DTC P0713 is output and hand −held tester output is −40 _C( −40 _F), there is an open circuit.
Measure the resistance between terminal THO1 (THO) 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.
1 CHECK OTHER DTCS OUTPUT(IN ADDITION TO DTC P07 11 )
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to the ON position and push the hand −held tester main switch ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read the DTCs using the hand −held tester.

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 park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that engine can be started
only when the vehicle is in P or N shift position.
When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N
or D, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.
