DTC P0712, P0713; Transmission Fluid Temperature Sensor "A" Circuit Low Input [08/2013 - 08/2014]: Description

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

The sensor resistance changes with the CVT fluid temperature. As the temperature rises, the sensor resistance decreases. The ECM applies voltage to the temperature sensor through ECM terminal THO1 and 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 traffic.
