Regen question

[Tqr6]

Ok it is a wiring issue,apparently the wires that come from the ecm have chaffed inside the loom from not being properly zipped tied and or secured when I had engine work done,it was riding in the back of the valve cover and has eaten though,I have started repairing wires and got it to regen, but if the loom moves I lose temps so I will have to chase the whole harness from the ecm to the fire wall on the passenger side, hope this helps anyone else..!
