\u00a9 2023 wikiHow, Inc. All rights reserved. I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..? 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 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. 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. Make sure the battery voltage is about 12.6 volts. By clicking Accept, you consent to the use of ALL the cookies. The Cummins ECM uses a Differential Pressure sensor to monitor exhaust flow through the filter.

Guys, my MD802 is telling me that the DPF is too clogged to regen so I'm assuming that it can only be cleaned by taking it out and manualy cleaning it , chemical or roding it out ?? Method . % 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 test runs for 30 to 60 minutes approximately. 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.

Active and stationary regeneration of the DPF will be disabled. The correct oil is hard to find and spendy . 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.

Engine misfire: 1654, 1655, 1656, 1657, 1658, 1659 You'll need a multimeter set to 20V and a pressure gauge to test it. Here's how to test the DPF. Fired her up and instantly got totally different readings with no error codes. . Variation: If you have trouble keeping the probes against the pins, opt to use ones that have alligator clips and attach them to the pins so you dont have to hold them in place. Check if the signal of the aftertreatment temperature sensors is within specifications. Diesel emissions systems rely on sensors to send signals to control modules when maintenance on the aftertreatment systems is required or when something is no longer functioning properly and requires a repair. Of course I would change the oil again . % wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Already tried 2, but thank you all the same. Noticed exhaust temp upstream of dpf was 650-750, then dropped to 350 after. of water; (5) exhaust cooling coil; and (6) a pump protective filter. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). 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 DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. DPF-R will do the trick used one for about 8000 miles with no problem.

Too spendy to have it serviced at MB or Dodge , money I don't have . The sensor monitors and measures the pressure with the EGR valve. I wish that would have been stated in the instructions from PPEI when I did the delete. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. Exhaust gas pressure - 120-150" Hg - Low could indicate a failing turbo. Free delivery for many products! Cummins Dpf Differential Pressure Sensor Reading If you are working in a diesel engine, then you know how important it is for the engine to have a good diesel particulate filter. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). stream The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. The operation of the Exhaust Gas Recirculation (EGR) valve will be disabled. 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 the soot load on the DPF is high, the ECM will activate the DPF system warning lamp on the dashboard. This leftover diesel fuel can wash away the oil film that protects internal engine components and can cause catastrophic failure. Previous Post The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. 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 exact location of the DPS varies by vehicle model type such as medium duty, pickup, or van. If we can find it, we should be able to cut post inject to next to nothing where as when the regen is initiated there is actually nothing happening externally but you are telling the ECM that is is happening and it's happy. : WL-D05013. If that doesn't work take it to a garage where they can force a regen using their equipment.. Hi.. well i couldnt find any examples on the of dpf traces on the current scope software. but there was a link to frank massey testing a dpf so hopefully that will give you some answers..if the link works, Fitted the replacement, second hand Sensor this morning, cleared the error codes and executed the "New DPF Sensor fitted" process to reset the ECU. 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 same scanner and love it. thanks, Frank. The ECM activates the fault codes based on the measured pressure difference across the DPF. the difference between the two measuring points. This helps determine if you need to clean or replace the filter to avoid clogs. If you still dont get a reading, then there may be a problem with your vehicles electrical system. At one point it reports the charge status of the particle filter and monitors its function. At ambient temperature26C (78F) and above:Voltage reading should be between 0.642 and 0.738 Volts. Since soot is abrasive, when it is mixed with oil, will cause premature wear to the engine components like the bearings. If I understand it correctly, this value is a discrepancy in the readings between the two sides of the sensor that the ECU learns and compensates for. The symptoms of a diesel particulate filter differential pressure sensor malfunction are not always easily detected because they mimic many of the symptoms of other components of the diesel emissions systems failing. %PDF-1.3 During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. If you notice the rubber hose has cracks or damage, replace it as soon as you can since it may leak later on. I listed the most important troubleshooting steps below.

However at higher rpm and load, things start to get crowded and that's where you'll see a difference. Learn more An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicles exhaust before and after it passes through a filter. If you don't notice a voltage change, first test all of their connecting hoses with a pressure gauge. DPF differential pressure sensor signal stuck-in-range. Category: Exhaust Pressure Sensor / DPF Sensor. But.even if you know the pressure how do you propose measuring it. 888.99.DIESEL. Appreciate 0 Quote . Using a pressure gauge, measure both hoses. $159.59. Last regen was about 900 kms ago. 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.

If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. It will need to either be removed, professionally cleaned, or replaced, both options being much more than the cost of diagnosing and replacing a faulty sensor. Subscribers do not see these advertisements, To join in you must be a member of MotorhomeFun. To protect the engine, the ECM activates the power derate. Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment.
