Diamante Sedan V6-2972cc 3.0L DOHC (1993)
Barometric Pressure Sensor: Description and Operation
Air Flow Sensor Location
Location
The barometric pressure sensor is located in the Air Flow Sensor (AFS).
Purpose
The Barometric Pressure Sensor measures atmospheric pressure and converts the measurement into a voltage signal which is sent to the 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.
