I’ve got a 2015 Ram 2500 6.7 Cummins. Over a month ago I started it up and the service throttle control light came on with very little throttle response. DTC codes were throttle sensor low voltage mass air flow high voltage. Couldn’t find any breaks or wires stripped so I changed the throttle position sensor it didn’t fix it. Had my mechanic look at it and reflashed the ECM and I’ve since changed the mass airflow sensor and inlet air pressure temp. There’s zero throttle response now and idles rough dtc codes are P2122 P1193 P0254 P0882 and the throttle position sensor low voltage code. Anyone had this happen? Truck is deleted with efi
