fault code ???

Hello, the airbag of my 307 2002 xt premium car broke out. airbag keeps giving fault warning. What should I do to get rid of the warning from this light and when I put the car to the test today, it gave 2250 unknown error warning. does anyone know what this code is ???

If the airbag breaks out, you will deceive the system but you will resist and the room will not be very durable & nbsp; other airbags will not hurt in the event of an accident or you will go out and get the airbag.

The front two airbags break out ... I don't think of the resistance. Because let's not get out of our humanity while selling both life and life .. :) I was curious about this malfunction code. because even when the fault lamp is not lit, when we connect it to the pc again, the code gave: p2250 unknown fault code

The link below says that there is a problem with the oxygen sensor voltage. Delete the error, drive a little bit, and then see if the error comes back.
