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.

Kia Stinger (CK) 2018-2023 Service Manual: How does the air bag system operate?
Air bags are activated (able to inflate if necessary) only when the Engine
Start/Stop button is turned to the ON or engine is running.
The appropriate air bags inflate instantly in the event of a serious frontal
collision or side collision in order to help protect the occupants from serious
physical injury.
There is no single speed at which the air bags will inflate.
