I have a 2011 ram 2500 with the 6.7 cummins. For the past few weeks the check engine light has come and gone. Now it is on permanently. Back at the dealership again. I have owned this truck for a little over a year and has been in shop probably seven times having sensors replaced. The current codes say 1. Fuel rail pressure sensor half circuit. 2. Oxygen sensor half circuit. The other 5 all say unknown codes. I did replace the back oxygen sensor a few days ago but showing codes again. Anyone else have any idea what's going on because the dealership obviously have no clue. I have drove it at highway speeds for over an hour and half to make it regen but still no change. If nothing else I am going to do full egr delete and new exhaust.
Thanks
