Transmission Fluid Temperature Sensor
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2002 Lincoln Navigator, 2002 Ford Expedition, 2001 Lincoln Navigator, 2001 Ford RV Cutaway, and 2001 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
Transmission Fluid Temperature (TFT) sensor is located on solenoid body assembly. PCM monitors voltage across TFT sensor to determine transmission temperature. Depending on temperature, PCM controls Electronic Pressure Control (EPC) pressure, shift scheduling and TCC operation. TFT sensor inhibits TCC operation during warm-up and locks TCC if transmission fluid temperature is too high. Malfunction of sensor will cause incorrect line pressure and possible lack of TCC operation.
