Kia Soul: Manifold Absolute Pressure Sensor (MAPS). Description and Operation
Kia Soul 2014-2019 PS Service Manual / Engine Control / Fuel System / Engine Control System / 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.
