Barometric & Manifold Pressure Sensor

The barometric and manifold absolute pressure (BMAP) sensor is actually two sensors combined in one assembly. The BMAP sensor monitors the value of the intake manifold absolute pressure and atmospheric pressure. Manifold absolute pressure is defined as barometric pressure minus manifold vacuum. Barometric and manifold pressure are converted into electrical signals for use by the ECA, which will use the signals to calculate spark advance, EGR flow and air/fuel ratio. The sensor is located on the right-hand fender apron.
