Peterbilt Cummins not regening

I have a 2019 Peterbilt x15 Before I get to start it codes 1921 differently pressure is on and ETC driver circuit 5879 code and I try to do a regen from truck it’ll kick out within minutes and then 1981 dpf system pops up and also 5882 ETC pops up. I can’t get the laptop to do the regen I was doing it yesterday but now I can’t. I did change the differential pressure sensor and cleaned up the pipe between EGR and ETC. This truck as always had ashload soot levels high and always use to just burn it off! But my question is. Is it the filter or the ETC Maybe the ETC is acting up cuz of the clogged filter? The 5882 code pops up shortly after I turn truck off

ETC IS ELECTRONIC THROTTLE CONTROL ACTUATOR
