Third generation YP (2014-2020) / Kia Sedona YP Service Manual / Engine Control / Fuel System / 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 that amplifies the element output signal. The element is silicon diaphragm type that adapts pressure sensitive variable resistor effect of semi-conductor.
Because one end of the silicon diaphragm is 100% vacuum and the manifold pressure applies to the other end, the sensor output can be achieved in analog signals from the silicon variation proportional to pressure change.
