Cummins Sensors provide a whole solution package, enabling system integration while meeting critical regulations. shipping them globally Explosion style low price we ship worldwide New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube masr-alyoum.com, C $125.06 Find many great new & used options and get the best deals for New Cummins DPF Differential . 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. Ash is stored in the DPF. Fwiw I am getting 2500hpa back press and 90hpa dpf diff cruising on level ground. So if the front hose reads 1 PSI and the rear hose reads half PSI, the signal wire voltage should read somewhere around .8 volts. The DPF sensor measures the pressure drop across a DPF. To replace it, simply remove the old one and replace it with the new one. DPF Parts Direct.com is more than an online store, were backed by parent company DES, with 15 years of hands-on shop experience with diesel emissions systems including retrofitting and 42 years of diesel repair experience. Simply the best offers on diagnostic tools for the US market. By clicking on them and completing a transaction on the merchants website, I earn a small commission at no extra cost to you. for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? . Product Detail. If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. Receive the latest updates on new posts, freebies and training courses. Depending on the measured soot load, engine torque output will be reduced. 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. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). 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. 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 . I had a conditional pass but only aloud that one time, now need to fool it or return to stock. The pressure sensor location is a bit different for each make and model. What is a DPF pressure sensor? You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. a static regen after replacing the Dpf pressure sensor seemed to remove the Dpf warning light (it only came on after replacing the sensor). The online store you use should provide you with access to industry experts to help you if you run into an unexpected problem changing the sensor. Ended up finding a lot more information I wanted to learn. DPF differential pressure: 1879, 1881, 1883 The sensor is located on the Aftertreatment system, mounted directly on the DPF. But.even if you know the pressure how do you propose measuring it. When you purchase through links on our site, we may earn an affiliate commission, which supports our community. Assuming that you validated your repair after each step that youpreviously followed (run engine, test drive etc): If fault code 1922 is still active OR inactive with more than one counts in the last 25 operating hours, the DPF is fully clogged. The engine should start with the signal wire back-probed. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. Email us for more detailstruckingandfixingwithryan@gmail.com------Disclaimer------The information and instructions provided by Trucking \u0026 Fixing with Ryan YouTube channel is for general informational purposes only. Using DDDL go to service routines> SCR & DPF voltages. Naturally, a small pressure drop is always expected even on new DPFs, due to the fact that the exhaust gases are foreced to flow through the DPF walls. :$:High tech old school and finally lovin it. This filter traps particulate matter (also called "soot") created by the engine. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. anyone know of what resistors can be used to fool the DPF sensor into thinking an active regen is working? 1 0 obj Vacuum pumps measure how much pressure builds up inside the sensor when you add more air. 1. Otherwise issues like you describe will occur. '6 sMZiMDLWzRu7h55 SDhGCp]%iO '#Tgq&YK_/inyx*TEa"|E$8qRB B8~ Pc#V. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. Exhaust Pressure Sensor 3921027401; Check my guide on how to create an account, training courses on how to use QuickServe Online effectively, you can even rent one from Diesel Laptops. If the measured temperature difference is within specifications, proceed to the next step. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. SKU: 904-7127 : Quantity: Share. We are also having troubles with dpf sensor. 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. 4.6 V depending on differential pressure. General DPF faults: 2754, 3133, 3134, 3135, 3316, 3317, 3318, 3319, 3321, 3322, 3396, 5383 Let me know if you figured it out and it works, as I'll need to do emissions and if that works I won't have to swap out the exhaust. You must log in or register to reply here. EGR differential pressure faults: 1866, 2273, 2274. Purchase your Cummins 2871960 DPF Differential Pressure Sensor here. 4954574 Genuine Cummins OEM NOX Inlet Temperature Sensor, New In Box, DPF Sensor.
