2012 Check engine light
I have a 2012 RGU with only 7k miles. Only engine mods are a high airflow air filter and a Vans & Hines LCD Fuelpak. I’ve ridden 5-600 miles since those mods. Today the check engine light came on.
The engine seems to run absolutely fine.
P0134 Front Oxygen Sensor Inactive (disconnected as part of the fuelpak upgrade)
P0154 Rear Oxygen Sensor Inactive (disconnected as part of the fuelpak upgrade)
P1356 Rear Cylinder No Combustion
P0572 Brake Switch Low
P0131 Front Oxygen Sensor Low / Engine Lean
C1094-Front brake switch always on
C1214 - unknown
