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. This filter traps particulate matter (also called "soot") created by the engine. By clicking on them and completing a transaction on the merchants website, I earn a small commission at no extra cost to you. Ended up finding a lot more information I wanted to learn. The pressure sensor location is a bit different for each make and model. If you don't notice a voltage change, first test all of their connecting hoses with a pressure gauge. Components not supplied by Cummins are not covered under this Plan. If you still dont get a reading, then there may be a problem with your vehicles electrical system. The correct oil is hard to find and spendy . The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. for example on a deleted truck that the aftertreatment system hasnt been disabled only codes shut off, the truck will want to go into a timed/forced regen even though there is no DPF. . my thoughts like i said were to manipulate the DPF sensor in a way that it would send the appropriate signals to the ECM telling that it is in DPF SENSOR !!!!!!!! The operation of the Exhaust Gas Recirculation (EGR) valve will be disabled. The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. Engine misfire: 1654, 1655, 1656, 1657, 1658, 1659 4954574 Genuine Cummins OEM NOX Inlet Temperature Sensor, New In Box, DPF Sensor. Frank Mc, have you gone ahead with the dpf delete? DPF differential pressure sensor signal voltage. I've got a long experience as technical trainer and training course developer. Check if the signal of the aftertreatment temperature sensors is within specifications.

You dont want to go to all the effort and spend valuable time and money replacing a sensor only to have it fail prematurely because it is a poor-quality replacement part. if not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). These cookies track visitors across websites and collect information to provide customized ads. If this happens, the DPF can become contaminated and eventually fail. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. I listed the most important troubleshooting steps below. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Aftertreatment 1 Diesel Particulate Filter Differential Pressure - Data Valid But Above Normal Operating Range - Most Severe Level. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. Check for EGR differential pressure sensor blockage. As implied by the name, it is responsible for continuously detecting the pressure difference between exhaust gases before and after the particulate filter.

I take it you've tried a second static burn? Diesel Particulate Filter (DPF) Pressure Sensors . Of course I would change the oil again . Hi I got the autel 802 code reader and it gives exhaust back pressure and DPF differential pressure. It should also carry a wide selection of sensors and have parts in stock. what im trying to do is to actualy fool the ecm into thinking it is performing a regen successfully when it goes into a timed (forced) regen. Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. By comparing the pressure at these two points, the sensor can track the buildup of soot within the DPF and trigger the PCM to do a regeneration cycle at the appropriate time. In today's video, Ryan is showing you the dignosis of replacement of cummins ISX15 DPF differential pressure sensor on his Kenworth T660.Announcement WE ARE GOING TO MID-AMERICA TRUCKING SHOW2023 Mid-America Trucking Show: March 30 - April 1, 2023 - Kentucky Exposition Center- Louisville, KYThursday, March 30 - VIP Session: 10AM - 1PM, Show Hours: 1PM - 6PMFriday, March 31 - Show Hours: 10AM - 6PMSaturday, April 1 - Show Hours: 9AM - 4PMRegister today with our code: HJFZBLMeet with us at 2023 Mid-American Trucking ShowOur Truck Repair Shop: Fox Truck \u0026 Tractor LLC (Truck Maintenenace, Repair \u0026 Inspection) https://www.foxtruckandtractor.com/Our Diesel Emission Shop: Diesel Emissions Specialists LLC (DPF, DOC, SCR \u0026 Full One Box Cleaning, Sensor Bung Replacement, TIG/MIG Welding \u0026 General Repairs)https://www.emissionspecialists.com/Our Truck Parts Sales: Diesel Truck Parts Store ( All-makes line of aftertreatment emissions parts, (with over 100 SKUs for DPFs / DOCs, over 45 clamps, over 110 gaskets, over 100 sensors, over 45 weld bungs, and over 30 charge air coolers \u0026 accessories), Used \u0026 Open Box truck parts)EMAIL/CALL US TODAY TO ORDER YOUR AFTERMARKET EMISSION PARTS FOR VERY AFFORDABLE PRICE!! The voltage should read a value between the pressure values of both hoses. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. 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 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. Poor engine performance; Poor . The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. Page 3 AS, S.L.U. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. 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. If the soot load is high, a higher pressure difference is observed, because the accumulated soot will provide a restriction to flow on the DPF inlet side (Inlet pressure > Outlet pressure). Why do so many guys on this forum change the Y-cable ? for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? Engine problems: If the engine has malfunctioned, it is possible that excessive soot is created, causing the DPF to get blocked. Check my guide on how to create an account or my training courses on how to use QuickServe Online effectively. The two pipes allow exhaust gas pressure from the inlet and outlet of the DPF respectively to reach the sensor. 1 0 obj 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. I just watched an active regen on my 2007 2500. I had a conditional pass but only aloud that one time, now need to fool it or return to stock. Replace the whole assembly). Level up your tech skills and stay ahead of the curve. Although a three tenths of a PSI doesn't sound like much, I still wonder if there . wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Otherwise, you can remove the sensor and test the electrical resistance between the ports. If they are blocked or need cleaning, remove the 3 plugs (underneath the mounting position of the sensor) to gain access to the drillings. Remove This . Perform the Aftertreatment Diesel Particulate Filter Regeneration Analyzer Test (ensure that you have at least 250 MB space on your hard drive). Noticed exhaust temp upstream of dpf was 650-750, then dropped to 350 after. 4 0 obj 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 will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. Avoid using your vehicle if you dont have the sensor attached since it will cause unfiltered exhaust fumes to escape. Well I just replaced the DPF differential pressure sensor and cleared the codes, however two codes came back . Here ya go, using the search function for this thread,, I have the three 100 OHM sims used for the DPF; Used very little until I went with EFI live, a couple of years ago. It's bad!!!!!! This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. Opt for a digital multimeter since they can perform multiple functions and will be easier to read while testing the sensor. Piss!!!!!!! I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..? Intake manifold pressure faults: 125, 2973, 4616 The signal output is described by a linear function: U = (0.82 x p +10) x 0.05 [V/kPa] Where: U = signal output voltage [V] DC p = differential pressure [kPa] Otherwise, connect your diagnostic tool and read the fault codes. The remaining DPF life is a calculated value based on a number of factors. Free shipping. You are using an out of date browser. While the engine is running you will then need to remove the hoses from the sensor. i also removed the hydrocarbon doser and cleaned that, along with cleaning the imap sensor, cleaning the egr differential ports and sensor, the exhaust back pressure sensor, and even replaced the exhaust pressure .
