Cummins provides sensors that support a multitude of critical components on your engine - from controlling the speed of the turbocharger to assisting the level of NOx taken into the aftertreatment system. Already tried 2, but thank you all the same. 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 sensor is located on the Aftertreatment system, mounted directly on the DPF. capacity of 0.250 L of air/min; (4) a pressure transducer capable of measuring to 0.1 in. a static regen after replacing the Dpf pressure sensor seemed to remove the Dpf warning light (it only came on after replacing the sensor).

I have same scanner and love it. Ok so in the last 5 min I made something work, using a MOSFET tied into a resistor representing the max resistance that we need to see for the EGTs, I can use the mosfet to ramp the resistance from OL al the way down to the 5ohm resistor at 5vdc, it works and I can step it in .003 ohm resolution. A Diesel particulate filter helps to trap dust and other debris that might otherwise cause the pressure to rise in your diesel engine. Disconnect the DPF pressure sensor connector. What to Look For in a DPF Differential Pressure Sensor That is Failing . The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. If this happens, the DPF can become contaminated and eventually fail. If you bring your filter into a DPFCleaning.com center, we'll check the filter over and give you a condition report as to whether the filter can be cleaned or not.

The multimeter should normally display a voltage between 4.5 to 5 volts for referencing the 5-volt, a solid 0 volts for the ground wire, and anywhere between 0.5 and 4.5 volts for the signal wire. thanks, Frank. Cummins DPF Differential Pressure Sensor - 2871960. I understand part of the initials ie damp proof but what does the f mean. This also happens when the sensor fails because it leads to the DPF becoming clogged. Include your email address to get a message when this question is answered. Check my guide on how to create an account or my training courses on how to use QuickServe Online effectively. use a multimeter and vacuum pump to test the pressure and voltage readings. stream idling) might require a stationary regeneration, due to the fact that the average temperatures on the DPF are not enough to allow soot to be burned off passively. I have that same scanner, it has allot of good info like that but if you don't know what parameters are good and or poor it's kind of useless. endobj %PDF-1.5 Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. But.even if you know the pressure how do you propose measuring it. The remaining DPF life is a calculated value based on a number of factors. 888.99.DIESEL. As I increase rpm to 2000 rpm (parked), back pressure increases to approximately 2000 hpa, and differential . My understanding is that the 40420 does not have DPF delete capabilities. The differential pressure sensor is one of the sensors in the diesel emissions system that communicates with ECU and the power-train control module (PCM) critical information about exhaust backpressure caused by the accumulation of diesel particulate matter (DPM) or soot.

The parts tend to make up the majority of the cost, usually between $100 and $400, while the labor might only be $50 to $100. 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. If they are blocked or need cleaning, remove the 3 plugs (underneath the mounting position of the sensor) to gain access to the drillings. I had issues with mine so. SKU: 904-7127 : Quantity: Share. %PDF-1.3 JavaScript is disabled. If any problems are found, check once more that you performed the checks correctly. The Cummins ECM uses a Differential Pressure sensor to monitor exhaust flow through the filter. Short the +5V SUPPLY pin to the Differential Pressure SIGNAL pin (NOT the outlet pressure signal pin! Differential Pressure Sensor (DPS) - Exhaust Pressure Sensor - RPF Pressure Sensor In the exhaust system of your vehicle, the differential pressure sensor measures the pressure upstream and downstream of the diesel particulate filter, i.e. If you want to check the sensor while its still attached to your vehicle, use a multimeter and vacuum pump to test the pressure and voltage readings. You can buy metal T-pins from hardware stores or online. Check if the signal of the aftertreatment temperature sensors is within specifications. Industrial differential sensors may be integrated into a standardised fitting, allowing it to be built into existing pipework. The vehicle then ran fine for about 197km then the background regens kicked in (no light on dash) and these were occurring every 1-16km according to Multiecuscan, which is when I get white smoke bellowing . If you don't notice a voltage change, first test all of their connecting hoses with a pressure gauge. ya EGR has A LOT of sensors/modules tied into it. i pretty much gave up on figuring out a way to simulate EGR readings which is why i left mine in tact just plug it all in for testing. The DPF differential pressure sensor is a different sensor that is necessary for filtration to function effectively. Thank you in advance for your support! Here are the DTC's 2079 , DPF differential press. Verify your repair and continue to the steps below. now are you positive resistors cant be used in the DPF sensor? You just pull the 2 rubber hoses off. Categories . In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. , 2501 boost pressure regulator signals fault 2626 DPF soot content too high for regen. One line is attached before the DPF. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. The cookie is used to store the user consent for the cookies in the category "Analytics". To reduce the possibility of personal injury, always ventilate the compartment before servicing the . The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. if so do you have any ideas as to what sensors can be manipulated manually in order to control (activate and deactivate/complete) a regen? If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. We changed B28/8 sensor, check cables resistance to ECU = 0,7 OHMS all three cables, and check the two small tubes to dpf for leaking all good like new, made two regeneration and mark in Xentry as DPF has been renew and still problem come on after 50 km or less.

Connect your preferred diagnostic tool, read and list all other active fault codes OR inactive fault codes with more than one counts in the last 25 operating hours. The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. Wiring harness: Incorrect wiring harness pin installation. <> 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%. It's going to want to close turbo down and open EGR valve until it see pressure Take the butterfly out of the throttle and leave EGR in place but blocked off with plates Then setup another resistant mosfet to simulate a pressure in the EGR to keep that readiness monitor happy. 2011,4wd LB/CC 2500 H&S Mini MCC by Tomeygun, BD protect 68rfe VB seperator plate enhanced stall triple disk TC, Super B 64.5/80/.91 3rd gen mani & inline EB, Arp 425s, Fass Titanium 95. In an analogue way the upper range 4.8V5.0V is also reserved for sensor diagnosis. anyone know of what resistors can be used to fool the DPF sensor into thinking an active regen is working? Figure 5.1 Correlating pressure signals to determine DPF transfer function They worked, but I had the CEL. 1 0 obj This image may not be used by other entities without the express written consent of wikiHow, Inc.
