DTC P0710-00: Transmission Fluid Temperature Sensor "A" Circuit Range/Performance [10/2015 - 11/2017]: Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. However, it is still accessible from the selected car via links, so may be relevant.

The ATF temperature sensor converts the automatic transmission 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 fluid temperature based on the voltage signal.
