Transmission Fluid Temperature (TFT) Sensor
The TFT sensor is located in the transaxle/transmission assembly. The PCM monitors voltage across the TFT sensor to determine transmission oil temperature. Depending on oil temperature, the 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.
