Description and operation
Manifold Absolute Pressure Sensor (MAPS) is a speed-density type sensor 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. This silicon diaphragm type element has pressure sensitive
variable resistor effect of semi-conductor. One side of silicon diaphragm is 100%
vacuum and manifold pressure is applied on the other side. Hence, output is gained
from the silicon variation in proportion to the pressure change.
