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”.

Approx. 80 _ C (176 _ F) (After Stall Test)
HINT:
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.

HINT:
If any other codes besides ”P0711” is output, perform the troubleshooting for those DTCs first.

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
*1or more than156 k*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.
*1:150_C (302_F) or more is indicated regardless of the actual ATF temperature.
*2:−40_C(−40_F) is indicated regardless of the actual ATF temperature.
HINT:
The ATF temperature can be checked on the hand−held tester display.
