The computer looks at these temperatures (in conjunction with the differential pressure sensor [DPF]) to infer the level of restriction in the system.Normally, your DPF should measure between 4.5 and 5mbar at warm idle. In steady-state conditions, your DPF should read around 40 to 50mbar. Your vehicle's DPF differential will show the amount of soot that's on the filter. If the DPF differential pressure is too high, the engine will need to regenerate.If the temps reach 525 or better and the inlet temp to the DPF stalls around 800 or is very very slow to reach 1000+ then something is wrong with the injector or DOC. Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valveThe DPF psi is a differential pressure between the inlet and outlet of the DPF so it's very sensitive and I'm not sure I can predict a regen from it.

The DPF on a cummins is big enough to sustain a healthy exhaust flow for about 700k+ miles, where ASH, not soot or coolant, will finally cause it to read above 3.0hpa on a constant basis (above 3.0 costs fuel mileage). However, the DPF is not a service-free system and will eventually require attention. The Single module system is so much smaller - does that mean I will use less DEF?
