Cummins Isx Normal Dpf Differential Pressure - Attached to each end of it are 2 small stainless tubes going to a sensor known as the dpf differential pressure sensor. That sensor tells the ecm how clogged up this soot. The differential pressure is 3. 9. The report i've got doesn't give the regen temps. All i have is the number of regens which is 461 with 4 incomplete. 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. Connect the aftertreatment diesel particulate filter differential/outlet pressure sensor to the oem harness. Install the differential pressure sensor tubes.
