Description and Operation
Description
Manifold Absolute Pressure Sensor (MAPS) is a speed-density type sensor and is installed on the surge tank.
The MAPS senses absolute pressure in surge tank and transfers this analog signal proportional to the pressure to the
ECM. The ECM calculates the intake air quantity and engine speed based on this signal.
This MAPS consists of a piezo-electric element and a 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 apply to the both sides of it respectively. That is, this sensor outputs the silicon variation proportional
to pressure change by voltage.
