CVT Fluid Temperature Sensor
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
The CVT fluid temperature sensor is installed to the control valve body and detects CVT fluid temperature in the oil pan.
The fluid temperature sensor uses a thermistor and changes the signal voltage by converting changes in the CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal voltage value.
