Kia Sportage: Engine Control System / Manifold Absolute Pressure Sensor (MAPS) Description and operation
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.

Your vehicle is equipped with an emergency liftgate safety release lever located
on the bottom of the liftgate. When someone is inadvertently locked in the cargo
area, the liftgate can be opened by pushing the release lever and pushing open the
liftgate.
