Barometric and Manifold Absolute Pressure (BMAP) Sensor

The BMAP sensor is actually two sensors combined into one assembly. This sensor monitors the absolute value of the intake manifold pressure and atmospheric pressure.

NOTE: Manifold absolute pressure is the difference between barometric pressure and manifold pressure.

Changes in atmospheric pressure are converted into an electrical signal and sent to the ECA. The ECA uses this signal to compensate spark advance and EGR rate for changes in altitude.

Changes in intake manifold pressure are converted by a pressure-sensing element into electrical signals for the ECA. The signal will vary according to engine load, vehicle speed and atmospheric pressure. This signal is used by the ECA to compensate spark advance and EGR rate to fit engine load.
