Transmission Fluid Temperature Sensor

The Transmission Fluid Temperature (TFT) sensor is located on solenoid valve body. PCM monitors voltage across TFT thermistor to determine transmission fluid temperature. Depending on temperature, PCM controls line pressure, shift scheduling and TCC operation. PCM also inhibits TCC operation when transmission fluid temperatures are low and determines PC solenoid operations. Malfunction of sensor will cause incorrect line pressure and possible lack of TCC operation.
