RE: Multiple emissions codes and probably wrong calibration.
Fan clutch is definitely bad. Also, after about a week of good fortune, my familiar trouble codes started coming back. Started with 3911, 4152, 6655, and 2771. These are the same ones that have been plaguing me for a year. Now I have a 0285 and 3714 and I am running at a level 2 derate. Getting fantastic fuel mileage though so I got that going for me.
