I had my car serviced recently for an A/C system repair. The third time I started the car, I got a Check Engine light that came on. The code I Read is P2229, "Barometric pressure sensor "A" circuit high.

I don't think the car has a MAP sensor. It doesn't appear on the Wiring diagram for the ECU. Is there a Barometric Pressure sensor somewhere? Could it be part of the Mass Air Flow Sensor?

Yes, you are correct, the Barometric pressure sensor is part of the MAF sensor, here is the location so you can check out the electrical connector for corrosion and if it is okay I would swap out the sensor. Here is the location. Check out the images (below). Please let us know what happens.
