FUNCTION AND OPERATION PRICIPLE
Manifold Absolute Pressure Sensor (MAPS) is speed- density type sensor and is installed on the surge tank. This
MAPS senses absolute pressure in surge tank and transfers this analog signal proportional to the pressure to the
PCM. The PCM calculates the intake air quantity and engine speed based on this signal. This MAPS consists of
piezo - electric element and hybrid IC that amplifies the element output signal. The element is silicon diaphragm type
and adapts pressure sensitive variable resistor effect of semi- conductor. 100% vacuum and the manifold pressure
applies to both sides of it respectively. That is, this sensor outputs the silicon variation proportional to pressure change
by voltage.

INSPECTION
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.
