Elantra L4-1595cc 1.6L DOHC 16 Valve (1995)
Barometric Pressure Sensor: Description and Operation
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 running and corrects the air-fuel ratio and the ignition timing, thus improving
driveability at high altitude.
