Barometric Pressure Sensor: Description and Operation
PURPOSE
Detects changes in atmospheric pressure related to changes in altitude from sea level.

OPERATION
As the vehicle changes altitude, air/fuel ratio adjustments are necessary to maintain good driveability and low emissions. PCME uses input from
this sensor to make needed adjustments.
