Order of inspection
P2227 Barometric Pressure Circuit Range/Performance Medium
The P2227 code means the barometric pressure (BARO) sensor is giving a reading that makes electrical sense but does not match what the computer expects. The main effect is a less precise mixture and less power, especially at altitude. You can keep driving, but the engine may feel a bit down on power.
