Engine Coolant Temperature Sensor

Engine Coolant Temperature (ECT) sensor is a thermistor which changes resistance with respect to coolant temperature. High temperature causes low resistance. Low temperature causes high resistance. A reference voltage (supplied and monitored by ECM) is modified by sensor resistance. ECM uses this information to control operation of various devices.
