Product Brief

KP21x/MAP

Integrated Pressure Sensor IC

for Manifold Air Pressure Measurement

Applications

Application

Typical Application

The manifold air pressure (MAP) is an important parameter to compute the air-

fuel ratio provided to the engine for lower emission due to better combustion

and increased efﬁciency. For cost sensitive engine systems a MAP sensor show

the potential to complement or even substitute mass air ﬂow (MAF) sensors. In

addition manifold pressure data can be used to compute diagnostics of leakages

and malfunctions of the exhaust gas recirculation valve. In automotive applications

where high production volumes are common there is substantial interest in

precision, low-cost and fully integrated sensors. In this context products of the

developed MAP sensor family KP21x are the optimum solution for aspirated or turbo

diesel and gasoline engines management systems.
