INTAKE AIR CONTROL SYSTEM ILLUSTRATION
The manifold absolute pressure sensor detects the manifold pressure by using a built-in sensor unit. The ECM determines the basic injection duration and injection advance timing based on the output voltage by the manifold absolute pressure sensor.
The manifold absolute pressure sensor monitors the absolute pressure inside the intake manifold (default is 0 kPa (0 mmHg, 0 in.Hg)), so that the ECM controls the air-fuel ratio at the proper level under any driving conditions, without the influence of fluctuations in the atmospheric pressure due to factors such as high altitude, etc.
