I was getting all of these codes at once. Before replacing anything, I decided to do some simple diagnostics and checks. I checked my 02 Sensor Fuse and surely it was BLOWN. I replaced the fuse and all these codes were gone. No more P1148, P1168, P1031 and P1051.
Check your fuse panel under the dash and look for the 15A – O2 Sensor fuse. Reference photo below:
