The 2012 Ford Focus houses the barometric pressure sensor within its intake manifold. This sensor, known as a modern version of the barometer, is a tool compatible with Arduino that measures atmospheric pressure in various settings. Such measurements assist in predicting immediate weather changes. The barometric air pressure sensor (BAP), a type of engine management sensor frequently present in vehicles, determines the atmospheric pressure surrounding the vehicle as it moves. This BAP functions similarly to the engine MAP sensor.
The barometric pressure sensor of the Ford Focus can be found positioned on the throttle body.
