Transmission Fluid Temperature (TFT) Sensor

TFT sensor is a thermistor (temperature sensitive resistor). PCM supplies a 5-volt reference signal through an internal resistor to sensor and measures return voltage. Monitored voltage is high when temperature is low (high sensor resistance), and low when temperature is hot.
