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.
