Monitor description
This dtc indicates that there is a problem with output from the atf temperature sensor and that the sensor itself is defective. The atf temperature sensor converts the atf temperature to an electrical resistance value. Based on the resistance, the ecm determines the atf temperature, detects open or short circuits of the atf temperature circuit, and detects faults in the atf temperature sensor.
Case 1 (2 trip detection logic): first, the ecm checks for the following conditions:
If the conditions are met, the ecm then checks if the atf temperature is less than 20°c (68°f). If so, the ecm interprets this as a fault and illuminates the mil.
Case 2 (2 trip detection logic): first, the ecm checks for the following conditions: (a)ect is 60°c (140°f) or more.
(B)after starting the engine and a certain period of time has elapsed, the ect is less than 35°c (95°f).
If the conditions are met, the ecm then checks if the atf temperature is 100°c (212°f) or more. If so, the ecm interprets this as a fault and illuminates the mil.

Inspection procedure
Hint:
Using the intelligent tester's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save 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.
Hint:
Measure the resistance between terminal tho1 (tho) and the body ground.
Hint:
If a circuit related to the atf temperature sensor becomes open, p0713 is set in approximately 0.5 Seconds.
It is not necessary to inspect the circuit when p0711 is set.
Result
Hint:
If any other codes besides p0711 are output, perform troubleshooting for those dtcs first.
Ok: automatic transaxle fluid level is correct.
Repair or replace transmission wire

Visually check the drain hole for coolant leakage.
If leakage is found, replace the water pump
assembly.
