Details Manifold Absolute Pressure Sensor (MAP)

The manifold absolute pressure sensor (MAP) informs the electronic control unit (ECU) the absolute pressure measured inside the intake manifold under the several operation conditions of the engine.

The value obtained is added to the information of air temperature. With these data, the system identifies the air mass that is being intake, calculates the progress of the ignition and the time for opening the injection nozzle, always looking for the ideal air/fuel ratio.

On older vehicles, the MAP sensor is fixed next to the engine and connected to the intake manifold through a hose.

In more modern vehicles, the MAP sensor is integrated and its function is to inform the pressure in the intake manifold and the temperature of the air. The sensor is directly fixed by screws on the intake manifold (it does not use a hose).
