Transmission Temperature Sensor/Switch: Description and Operation



Transmission Fluid Temperature (TFT) Sensor

The transmission fluid temperature (TFT) sensor is a thermistor-type sensor that varies a reference voltage signal. The resistance in the TFT varies with temperature. The powertrain control module (PCM) monitors the voltage signal across the TFT, and uses this information to determine the transmission fluid temperature.

The TFT is located on the main control body wiring harness assembly.

The PCM uses the TFT signal to help determine shift scheduling, torque converter clutch operation and electronic pressure control (EPC).
