Transmission Fluid Temperature Sensor: Description and Operation
-
The transmission fluid temperature (TFT) sensor is a thermistor-type sensor thet varies a reference voltage signal. The resisrance 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).
