Manifold Absolute Pressure Sensor: Description and Operation
MAP Sensor 20V
The Manifold Absolute Pressure Sensor is integrated inside the Motronic ECM and therefore does not have a connection pin on the ECM.
The pressure sensor measures the intake manifold pressure. The sensor converts the intake manifold pressure into an electronic signal and uses this
signal to control charge pressure.
