Default 2016 Big Horn 6.7l Diesel P225c and P2281 codes

I have these two codes that recently came up. Have been unable to locate what they are for or how to correct the problem. Does anyone have any information regarding these codes. Thanks

P225C Nox sensor stuck high.

P2281: Air leak between mass air flow sensor, and throttle body.
