Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). If the aftertreatment DPF differential pressure sensor voltage readings are within specification, then proceed to the Linked Solutions section. For a better experience, please enable JavaScript in your browser before proceeding. I'd like to get the GDE tune and am also considering deleting the DPF because I want a reliable van that doesn't leave me stranded hours from home on a regular basis. The ECM activates the fault codes based on the measured pressure difference across the DPF.

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. 99% Same Day Shipping - Multiple U.S. Cummins DPF Differential Pressure Sensor - 2871960. Any purchases you make on Amazon will help support this channel.http://amzn.to/2mALgqSFeel the need. There are a lot of possible faults that could be triggering fault code 1922. While the engine is running you will then need to remove the hoses from the sensor. Disconnect the DPF pressure sensor connector. For a better experience, please enable JavaScript in your browser before proceeding. You may be reading this as you've got code OBD Code P244B - Diesel Particulate Filter Differential Pressure Too High. a static regen after replacing the Dpf pressure sensor seemed to remove the Dpf warning light (it only came on after replacing the sensor). Purchase your Cummins 2871960 DPF Differential Pressure Sensor here. If the sensor values on step 5 meet specifications, it is necessary to check the sensor voltage readings further. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Once the test is completed, record the results and follow the instructions on the diagnostic tool. What to Look For in a DPF Differential Pressure Sensor That is Failing . wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Differential pressure switches that are out of calibration have a tendency exponential the further up the scale you go. JD. We know the equipment AND service end of the emissions industry! If everything passes a physical inspection and cleaning the sensor doesnt work, you can test the DPF sensors using a multimeter set to 20V and a pressure gauge. Damaged DPF. w4wn said: You need to leave the pressure sensor module connected to the wiring harness. This also happens when the sensor fails because it leads to the DPF becoming clogged. I have same scanner and love it. Using a pressure gauge, measure both hoses. This website uses cookies to improve your experience while you navigate through the website.

This article was co-authored by wikiHow staff writer, Hunter Rising. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape. % Depending on the measured soot load, engine torque output will be reduced. wikiHow is where trusted research and expert knowledge come together. 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. 4 0 obj Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. A forum community dedicated to Dodge Cummins Diesel truck owners and enthusiasts. Engines that operate longer periods on light loads (eg. There are 251 fault codes for this engine line. You'll need a multimeter set to 20V and a pressure gauge to test it. To test if your battery is working properly, you'll need to connect the multimeter ground with one lead connected directly onto its negative terminal and run a quick "plausibility" check. Check for EGR differential pressure sensor blockage. The DPF differential pressure sensor (DPS) has two pressure sample lines. The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. The newsletter contains updates about new freebies, posts and new training courses that become available. 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. If you replaced the assembly, validate your repair and then proceed to the next step. Common Rail Diesel engines have become more common in passenger vehicles in the past decade or so. 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] The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. Find many great new & used options and get the best deals for Dorman - HD Solutions DPF Differential Pressure Sensor 904-7106 Fits 2009-07 at the best online prices at eBay! Hunter holds a BFA in Entertainment Design from the University of Wisconsin - Stout and a Minor in English Writing. Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed. New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube. Remove I've got a long experience as technical trainer and training course developer. It is extremely frustrating when a work truck that is supposed to earn you money is unable to do what it is designed to do because a sensor has failed, and it is even worse when it breaks down and then requires a mobile mechanic and/or a tow to a repair shop to get it fixed and back on the road. DPF differential pressure sensor tubes to achieve a 010 degree sensor tube downward angle. Since soot is abrasive, when it is mixed with oil, will cause premature wear to the engine components like the bearings. Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged.
