DTC P0710-15: Transmission Fluid Temperature Sensor "A" Circuit Short to Battery or Open [10/2014 - ]: Description

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

The ATF temperature sensor converts the fluid 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 becomes higher, the sensor resistance decreases.

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

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