A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot. Check for EGR differential pressure sensor blockage. Warehouses - Fleet or Partner Pricing Available. If we can find it, we should be able to cut post inject to next to nothing where as when the regen is initiated there is actually nothing happening externally but you are telling the ECM that is is happening and it's happy. Aftertreatment - International - Cummins In theory, theory and practice are the same. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. I would always suggest to use a tool such as Cummins Insite or TEXA (you can even rent one from Diesel Laptops). Piss!!!!!!! correctly.

Diesel DPF Problems Solved - DPF Differential Pressure - what's The code DOES NOT mean that the DPF needs to be replaced immediately. When the diesel particulate filter is not regenerating properly due to the faulty DPF sensor failing you may experience some of or all of the below symptoms: A DPF pressure sensor is necessary to keep the DPF free from diesel particulate matter and soot, and if the DPF is plugged, the regeneration process will not fix it. The DPF differential pressure sensor (DPS) has two pressure sample lines. Thanks for posting the results.
