Barometric Pressure Sensor: Description and Operation

Barometric Pressure Sensor

PURPOSE

The Barometric Pressure Sensor measures atmospheric pressure and converts the measurement into a voltage signal which is sent to the Engine
Control Module (ECM)

The ECM uses the voltage signal to adjust the air-fuel ratio and ignition timing for the altitude at which the vehicle is running, thus improving
driveability at high altitude.
