It's possible that a vacuum line got disconnected. The same thing happened to me when I replaced my power steering pump. In my case, the tiny check valve attached to one of the rubber sleeves came off. Surprisingly, didn't affect drivability but did set the air injection code every 2nd or 3rd time I started the car after resetting the code.
