Transmission Fluid Temperature (TFT) Sensor
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The Transmission Fluid Temperature (TFT) sensor twist-locks into the solenoid body. The TFT sensor is a temperature-sensitive device called a thermistor. As the TFT rises, the TFT sensor resistance decreases. The PCM monitors the voltage across the TFT sensor to determine TFT. The PCM uses the TFT sensor signal as an input to determine cold and hot temperature shift and Torque Converter Clutch (TCC) operation.
