My 2020 RAM 2500 got a check engine code P20EE (SCR Catalyst Efficiency Below Threshold).
The truck only has 8000 miles on it.
I haven't done any mods to motor yet, just a Bank Pedal Monster and OBD2 splitter for AMP steps.
I haven't noticed any difference in performance, just mileage drop.
Code popped up after I hooked up the OBD2 splitter and drove a few miles, but I don't think that will cause a code for emissions, right?
I cleared the code and unhooked the OB2 splitter.
Does anyone have any ideas?
I have DPF/EGR deletes and a few Banks parts just haven't been installed yet waiting on the tuner and tunes.
Thanks.
