DTC P0712: Transmission Fluid Temperature Sensor "A" Circuit Low Input; DTC P0713: Transmission Fluid Temperature Sensor "A" Circuit High Input: Description

The CVT fluid temperature sensor converts the fluid temperature into a resistance value which is input into the ECM.

The sensor resistance changes with the transmission fluid temperature. As the temperature rises, the sensor resistance decreases. The ECM applies a voltage to the temperature sensor through ECM terminal THO1, and the ECM calculates the fluid temperature based on the voltage signal.

HINT:

The CVT fluid temperature is likely to increase under conditions such as towing, climbing hills and in heavy traffic.
