Transmission Oil Temperature (TOT) Sensor

TOT sensor is a thermistor that changes resistance as transmission fluid temperature changes. Sensor resistance decreases as fluid temperature increases. Sensor resistance variation is converted into a voltage signal and sent to PCM. PCM uses this input signal to determine transmission fluid temperature.
