Barometric Pressure Sensor: Description and Operation
Description
The barometric pressure sensor installed on the volume air flow sensor senses the barometric pressure and converts it into a voltage which is sent
to the engine control module.
The engine control module uses this signal to compute the altitude at which the vehicle is running and corrects the air-fuel ratio and the ignition
timing, thus improving driveability at high altitude.
