Barometric (BARO) Pressure Sensor

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