Hyundai Accent: Manifold Absolute Pressure
Sensor (MAPS). Description and Operation
Description
Manifold Absolute Pressure Sensor (MAPS) is a speed-density
type sensor and is installed on the surge tank. It senses absolute pressure
of the surge tank and transfers the analog signal proportional to the pressure
to the ECM. By using this signal, the ECM calculates the intake air quantity
and engine speed.
The MAPS consists of a piezo-electric element and a hybrid
IC amplifying the element output signal. The element is silicon diaphragm type
and adapts pressure sensitive variable resistor effect of semi-conductor. Because
100% vacuum and the manifold pressure apply to both sides of the sensor respectively,
this sensor can output analog signal by using the silicon variation proportional
to pressure change.
