Hyundai Accent: Engine Coolant Temperature
Sensor (ECTS). Description and Operation
Description
Engine Coolant Temperature Sensor (ECTS) is located in the
engine coolant passage of the cylinder head for detecting the engine coolant
temperature. The ECTS uses a thermistor that changes resistance with the temperature.
The electrical resistance of the ECTS decreases as the temperature
increases, and increases as the temperature decreases. The reference +5V is
supplied to the ECTS via a resistor in the ECM. That is, the resistor in the
ECM and the thermistor in the ECTS are connected in series. When the resistance
value of the thermistor in the ECTS changes according to the engine coolant
temperature, the output voltage also changes.
During cold engine operation, the ECM increases the fuel
injection duration and controls the ignition timing using the information of
engine coolant temperature to avoid engine stalling and improve drivability.
