Cummins ISX CM871 Regen Temps Question

Diesel Force Comprehensive Maintenance System
When a DOC starts acting up, especially with that 1691 code, this service by Diesel Force will fix the problem. It doesn’t matter if it is the dosing valve or the DOC, it fixes it. It costs about $300 and takes about 2 hours. They don’t even remove any of the components and the EGR and exhaust system is cleaned while the engine is running. This is the new way to deal with all EGR problems.

 

Does anyone know what would cause the regen temps to sky rocket up to 1200+ degrees after running almost perfect for the first 30 minutes of the regen? Truck came in with all the sensors and sensor module on the scr melted.The fuel dozer is new and it was plugged with soot so I replaced it. DOC and DPF are clean and no fluids in the down pipe. If someone could give me some components to monitor on insite during a regen that would help a lot...
