DTC P0711: Transmission Fluid Temperature Sensor "A" Performance [08/2019 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The ATF (Automatic Transmission Fluid) 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 temperature based on the voltage signal.

DTC Code	DTC Detection Condition	Trouble Area
P0711	Either of the following condition is met (2-trip detection logic): Certain monitor enabling conditions are met and the ATF temperature is below 20°C (68°F). Certain monitor enabling conditions are met and the ATF temperature is 95°C (203°F) or higher.	No. 1 ATF temperature sensor (transmission wire)
