codes?

I have an early 99 f250 I have to codes on is P0470 it say Exhaust back pressure sensor circuit malfunction. The other is P1211 Injector control presser higher or lower then desired engine running. What could be causing these code to shoot and how can I fix them?

Both are very common. ICP can be caused from a chip
