P0710

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

DESCRIPTION

P0710-P0713:

The Automatic Transmission Fluid (ATF) temperature sensor converts the ATF temperature into a resistance value which is input into the ECM.

The ECM applies a voltage to the temperature sensor through ECM terminal THO1.

The sensor resistance changes with the ATF temperature.

One terminal of the sensor is grounded so that the sensor resistance and voltage decrease as the temperature becomes higher.

The ECM calculates the ATF based on the voltage signal.

MONITOR DESCRIPTION
ATF temperature sensor converts ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an open or short in the ATF temperature circuit. If the resistance value of the ATF temperature is less than 79 Ohms*1 or more than 156 Ohms*2, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will illuminate the MIL and store the DTC.

HINT:
- *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.
- The ATF temperature can be checked on the intelligent tester display.

WIRING DIAGRAM

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.

1. Warm up the engine.
2. Turn the ignition switch OFF.
3. Connect the intelligent tester to the DLC3.
4. Turn the ignition switch ON.
5. Turn the intelligent tester ON.
6. Enter these menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.





7. Follow the instructions on the tester and read the DATA LIST.





HINT:
- When DTC P0712 is output and the intelligent tester output is 150°C (302°F) or more, there is a short circuit.
- When DTC P0713 is output and the intelligent tester output is -40°C (-40°F), there is an open circuit. Measure the resistance between terminal THO1 (OT) and the body ground.
