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.
Temperature DisplayedMalfunction
–40C (–40F)Open circuit
150 (302 Short circuit
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.
