FUNCTION AND OPERATION PRICIPLE
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 whose resistance changes with the
temperature. The electrical resistance of the ECTS decreases as the temperature increases, and increases as the
temperature decreases. The reference 5 V in the PCM is supplied to the ECTS via a resistor in the PCM.That is, the
resistor in the PCM 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 PCM increases the fuel injection duration and controls the ignition timing using the
information of engine coolant temperature to avoid engine stalling and improve drivability.

FUNCTION AND OPERATION PRICIPLE
Knocking is a phenomenon characterized by undesirable vibration and noise and can cause engine damage. Knock
Sensor (KS) senses engine knocking and the two sensors are installed inside the V- valley of the cylinder block. When
knocking occurs, the vibration from the cylinder block is applied as pressure to the piezoelectric element. At this time,
this sensor transfers the voltage signal higher than the specified value to the PCM and the PCM retards the ignition
timing. If the knocking disappears after retarding the ignition timing, the PCM will advance the ignition timing. This
sequential control can improve engine power, torque and fuel economy.
