We don't have a list of codes yet, so the best we can do is guess. The codes are often related to each other, so I would focus my attention on the last two codes that we know from the 800 ETEC. So I'm guessing the exhaust sensor or module. There is a module near the front of the tuned pipe on the right side that comes loose and needs to be zip tied.

Guesses.......
P0680 - system reference voltage exceeded allowable variance (muffler temp sensor?)
P0160 - no activity detected on circuit (Exhaust module?)
P0426 - Exhaust Muffler Temperature Sensor Functional Problem
P0428 - Exhaust Muffler Temperature Sensor Open Circuit


Here are some other codes that we have been able to pin-point through various experiences, and two more guesses from those.

P0270 MAG Boost Injector Circuit Low
P0273 PTO Boost Injector Circuit Low
Possible Cause: Pinched wire or Fuel Controller

Guesses
P0271 MAG Boost Injector Circuit High
P0274 PTO Boost Injector Circuit High
