So b4 i bring it into the dealership i have been getting 2 codes 1 for egt sensor #5 P2482 and p20BD, reductant heater 2 control circuit.

EGT Sensor 5 i already ordered and will be here tomorrow that’s pretty straight foward , however

curious is reductant heater 2 the line part # 84749035? That long hose / pipe that goes from looks like def tank through chassis somewhere ( anyone have a diagram of it . Also which is reductant heater 1? )
You guys think i should start with that above part # , i can’t find much on p20BD code ?
