What make and model do you have? From my experience and according to the factory service manual the Barometric Pressure (BARO) sensor is integral to the "Multifunction Intake Air Sensor (Also known as the Mass Air Flow (MAF) Sensor). On most newer models the BARO, MAF and IAT sensors are all in one unit.
