During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. NEW Genuine Cummins OEM differential pressure sensor 4384138. The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. Took her out for a spin and to fuel her up (I read somewhere that the DPF will not regenerate if either you've got less than 20 ltrs of fuel or the Oil degredation is below a certain level), by the time I got to the fuel station the DPF Clogging % had dropped to 26.4% so it looks like all is rosey in the garden (fingers crossed). You can buy vacuum pumps online or from auto part stores. The DPF system is still used on commercial trucks today. Exhaust Pressure Sensor 3921027401; If you notice the numbers changing on the multimeter display, then the sensor has electrical resistance, meaning a current can pass through it and it will still work in your vehicle. Last regen was about 900 kms ago. The DPF differential pressure sensor is a different sensor that is necessary for filtration to function effectively. Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). Replace the DPF. O'Rileys Autos - Mobile Mechanic & DPF Cleaning 16.1K subscribers Subscribe 58K views 8 months ago diagnosing a diesel particulate filter differential pressure sensor 1: check voltage. Don't know but mine is in limp mode at the moment and I'm told from initial diagnostics that the soot level is 2%. I played with my truck and found I can run the CMC tier3 ECM on my truck and everything runs like a champ, its only a 260hp tune at 3000rpm high idle but it worked working on how to bump max speed on that ECM with EFI Live as we speak. , 2501 boost pressure regulator signals fault 2626 DPF soot content too high for regen. w4wn said: You need to leave the pressure sensor module connected to the wiring harness. You just pull the 2 rubber hoses off. This image may not be used by other entities without the express written consent of wikiHow, Inc.

The Cummins ECM uses a Differential Pressure sensor to monitor exhaust flow through the filter. The DPF differential pressure sensor is located on the back of your car's engine compartment. This also happens when the sensor fails because it leads to the DPF becoming clogged. Typically, the sensor is held in place with a Torx bolt and screws. That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. Send email to us. I take it you've tried a second static burn? The DPF sensor measures the pressure drop across a DPF. Check for EGR differential pressure sensor blockage. P r e p a r a t o r y S t e p s WA R N I N G Batteries can emit explosive gases.

This step will only work if you use Cummins Insite (version 8.5.2 or later) or an equivalent diagnostic tool which supports the test described below. Your exhaust gas flow at idle is not very restricted by your DPF even when mostly clogged. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. What to Look For in a DPF Differential Pressure Sensor That is Failing . You must log in or register to reply here. Not yet, i dont want to keep doing them.
