Barometric (BARO) Pressure Sensor

Sensor is incorporated into Volume Air Flow (VAF) sensor assembly, except on Mirage 1.5L. On Mirage 1.5L, barometric pressure is obtained from MAP sensor at key on, engine off. BARO sensor converts barometric pressure to an electrical signal, which is sent to ECM/PCM. ECM/PCM adjusts air/fuel ratio and ignition timing according to altitude.
