DTC P0710-00: Transmission Fluid Temperature Sensor "A" Circuit Range/Performance [10/2021 - 10/2022]: Description

The ATF temperature sensor converts the automatic transaxle fluid (ATF) temperature into a resistance value for use by the ECM.

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

The sensor resistance changes with the ATF temperature. As the temperature rises, the sensor resistance decreases.

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

The ECM calculates the ATF temperature based on the voltage signal.
