Kia Carens: 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.

Other information:
The wheels on your vehicle were aligned and balanced carefully at the factory
to give you the longest tire life and best overall performance.
In most cases, you will not need to have your wheels aligned again. However,
if you notice unusual tire wear or your vehicle pulling one way or the other, t ...
WARNING
All occupants of the vehicle must wear their seat belts at all times. Seat
belts and child restraints reduce the risk of serious or fatal injuries for all
occupants in the event of a collision or sudden stop. Without a seat belt, occupants
could be shifted too close to a deploying air bag ...
