Engine Coolant Temperature (ECT) Sensor

ECT is located on thermostat housing. ECT monitors coolant temperature and sends a voltage signal to PCM. ECT has a built-in thermistor, whose resistance varies according to coolant temperature. PCM determines engine temperature based on output voltage of ECT to provide optimum mixture enrichment when engine is cold.
