The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).
The MAP sensor measures pressure in the engine's inlet manifold. When coupled with data regarding the engine's revolutions per minute, or RPM, and a table of volumetric efficiency over the operating range of the engine, the MAP sensor can be used by the engine management computer to calculate fuel requirements.
