Transmission Fluid Temperature (TFT) Sensor

This sensor is located in the transaxle solenoid body. It is a temperature-sensitive device called a thermistor. The resistance value of the TFT  sensor will vary with temperature change. The PCM monitors the voltage across the TFT  sensor to determine the temperature of the transmission fluid.

The PCM uses this initial signal to determine whether a cold start shift schedule is necessary. The cold start shift schedule allows delayed shifts when the transmission fluid is cold to help warm the transmission fluid. The PCM also inhibits TCC  operation at low transmission fluid temperatures and adjusts LPC  pressures for temperature.
