Transmission Fluid Temperature Sensor
The Transmission Fluid Temperature (TFT) sensor is located near shift solenoids on valve body in transaxle/transmission assembly. Powertrain Control Module (PCM) monitors voltage across TFT sensor to determine transmission oil temperature. Depending on oil temperature, the PCM controls electronic pressure control pressure, shift scheduling and Torque Converter Clutch (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.
