DTC P0711 Transmission Fluid Temperature Sensor A Performance

DESCRIPTION

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

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. After running the vehicle for a certain period, the ATF temperature should increase. When the ATF temperature is below 10°C the ECM interprets this as a fault, turns on the MIL.

Wiring Diagram:

HINT: According to the DATA LIST displayed by the OBD II scan tool or intelligent 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.

NOTICE: In the table, the value listed under Normal Condition are reference values. Do not depend solely on these reference values when deciding whether apart is faulty or not.

1. READ DATA LIST
a. Warm up the engine.
b. Turn the ignition switch off.
c. Connect the OBD II scan tool or intelligent tester to the DLC3.
d. Turn the ignition switch to the on position.
e. Turn on the tester.
f. Select the item DIAGNOSIS / ENHANCED OBD II / DATA LIST.

g. According to the display on the tester, read the DATA LIST.

HINT: When DTC P0712 is output and OBD II scan tool or intelligent tester output is 150°C (302°F) there is a short circuit. When DTC P0713 is output and OBD II scan tool or intelligent tester output is -40°C (-40°F) there is an open circuit. Measure the resistance between terminal TH01 (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.
