Codes P0400 and P0403?

Okay, I’ve been dealing with P0400 and P0403, so I’ve replaced the EGR valve entirely along with the pigtail which all along I suspected that as the problem as over time the wires had hard bends through the wires, but it didn’t fix the problem so I replaced the EGR cause I kept trying to clean it. No luck! So, while taking the EGR off I noticed the transmission cooler hose connection was practically broken off from the cooler. So, I really expected that to be the issue at this stage cause prior I had T touched that cooler at all so the welds on them just gave way over time. No luck after replacing it. So, I once again look at live data not that I honestly understand what I’m looking at though, but I did notice the EGR command duty sat on 0% in park and while driving so it’s basic my dead or just simple not getting the power command signal, I assume. I’m going to attach the live data for you to see as well. So, prior to this happening I replaced the engine heater valve with the one that has a line hose connection because I have no heat in the car or all that didn’t fix the problem for the heat though I was told it would restore the heat. Probably the actuator in all honesty but I just haven’t gotten under there to pull it off to check. Do you think the wiring on tbar hearer valve could be the problem thou I do not get any error codes on it unless I have unplugged it or something. I honestly don’t know if my heater core is clogged or not.
