Barometric Pressure Sensor: Description and Operation
BAROMETRIC PRESSURE SENSOR (BPS)
The barometric pressure sensor installed on the VAF Sensor senses the barometric pressure and converts it into a voltage which is sent to the
ECM. The ECM uses this signal to compute the altitude at which the vehicle is operating and corrects the air fuel ratio and the ignition timing, thus
improving driveability at high altitude.
