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: 1879, 1881, 1883 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] Connect your diagnostic tool and monitor the fault code page. Next Post . Fault codes 1879 and 3134 should become active. now are you positive resistors cant be used in the DPF sensor? An air leak would change the sensor readings, thus resulting in the code. Once the test is completed, record the results and follow the instructions on the diagnostic tool. Exhaust Gas Recirculation (EGR): 1228, 1896, 2272, 2349, 2353, 2357, 2961, 2962, 3136, 3137, 3138, 3342, 3382, 3383, 3389 You are using an out of date browser. The DPF sensor measures the pressure drop across a DPF. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. 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 . One line is attached before the DPF. I understand part of the initials ie damp proof but what does the f mean. Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Going to get it on a mates pit at weekend and double check for blockages in the sensor pipes more thoroughly, mine sits at max 14mbar whilst idling which still seems high, possibly. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. Check for EGR differential pressure sensor blockage. Keep your vehicle turned off while youre plugging in the pins so you dont risk getting shocked. Also check for pin-to-pin short circuits. It's important to rev the engine and check for voltage changes before testing anything else. First, check your Cummins DPF Differential Pressure (DPF) Sensor Reading. DPF-R will do the trick used one for about 8000 miles with no problem. If you still dont get a reading, then there may be a problem with your vehicles electrical system. National Truck Parts has a large selection DPF and emissions products for heavy duty trucks. Sent from my H1611 using Tapatalk. At the other point it is used to control the low-pressure exhaust gas recirculation. If you replaced the assembly, validate your repair and then proceed to the next step.

Last Updated: April 6, 2020 A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF. The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. Enter your email address to receive access to exclusive offers. 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. For many years, operators of commercial trucks have been trying to increase uptime and minimize unscheduled and costly roadside repair events. DPFE Sensor Replacement Cost. This helps determine if you need to clean or replace the filter to avoid clogs. one on each side of the DPF, and it takes a reading of the pressure differential between the two. During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. Product Detail. DPF differential pressure sensor tubes to achieve a 010 degree sensor tube downward angle. The sensor hoses can become clogged from soot in the exhaust system just like the DPF. Steps. In this manner, the sensor is able to determine the pressure difference across the DPF, which serves as the primary input data the PCM uses to determine the soot load, and therefore, the efficiency of the DPF. It should also carry a wide selection of sensors and have parts in stock.

Level up your tech skills and stay ahead of the curve. We proudly carry Redline Emissions Products differential pressure sensors for many makes and models, and our parts meet or exceed OEM parameters.

Include your email address to get a message when this question is answered. This DTC is a two trip fault. if i can manipulate the DPF sensor to try and control and fool the ecm into thinking the regen cycle is working and complete it i can then have a deleted truck that will pass obd2 emissions. Use a wire to see if the ports are free of soot all the way to allow pressure to reach the sensor. At Balance Motor Works we take a holistic approach to DPF problems. One of the major complications these suffer from is the DPF - the Diesel Particulate Filter. When diesel particulate matter blocks one or both of these airways to the sensor, the sensor can no longer accurately determine pressure changes, which can result in catastrophic damage to the DPF and ultimately the engine. Already tried 2, but thank you all the same. How does a DPF pressure sensor work?
