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. The sensor is located on the Aftertreatment system, mounted directly on the DPF. Monitor DPF outlet pressure sensor voltage pin . For a better experience, please enable JavaScript in your browser before proceeding. Piss!!!!!!! When you troubleshoot any possible active fault codes from the list above, proceed to the next steps below to eliminate all other possibilities. Although a three tenths of a PSI doesn't sound like much, I still wonder if there . 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. References. 99% Same Day Shipping - Multiple U.S. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. Ok so in the last 5 min I made something work, using a MOSFET tied into a resistor representing the max resistance that we need to see for the EGTs, I can use the mosfet to ramp the resistance from OL al the way down to the 5ohm resistor at 5vdc, it works and I can step it in .003 ohm resolution. if it was fully clogged), then proceed to step 9. Also again ,, I know that I am running the wrong oil [ 229.5 instead of the 229.51] but I'm planning on a GDE delete of EGR and DPF so I'm thinking it will be OK to run this oil after the delete . Le migliori offerte per Cummins DPF Exhaust Temperature Sensor Thermistor 18 Lead 229538 sono su eBay Confronta prezzi e caratteristiche di prodotti nuovi e usati Molti articoli con consegna gratis! <> If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 Cummins Exhaust Temperature Sensor OEM 4954574. $125.00. Adding another set of data-points from a 2007 3500 with recent recurring, key-cycle resettable LHM issues and a 2626-1 DTC as shown on my new MD802 scanner: Exhaust Back Pressure at idle - 1517 hPa. These diagnostic trouble code refer to the condition of the exhaust gas You just pull the 2 rubber hoses off. Lastly, check the signal voltage one last time. One sensor that keeps an Eagle Eye on the condition of the DPF is the Differential Pressure Sensor.How can we test this sensor and how can we be sure that the ECU is processing what it sees? i know there are 4 levels that the DPF sensor will assume the filter is becoming blocked which will trigger a regen if i can find out what size resistors can be used to simulate that the filter is "cleaning" then maybe its possible to fool a deleted truck into thinking it successfully performed a regen? While there seems to be benefits to these computer managed engines, they bring a list of problems as well.

Avoid removing both hoses from the pressure sensor since you wont produce accurate results. Diesel Oxidation Catalyst (DOC) faults: 3313, 3314, 3315, Faults that could be causing excessive soot generation, Fuel System faults: 559, 1139, 1141, 1142, 1143, 1144, 1145, ,4713 The cookie is used to store the user consent for the cookies in the category "Analytics". $104.63 + $12.00 shipping . The sensor monitors and measures the pressure with the EGR valve. At one point it reports the charge status of the particle filter and monitors its function. For this investigation, an SKC pocket pump with integral pressure transducer (SKC Inc., Eighty-Four, PA) was used to collect the . My understanding is that the 40420 does not have DPF delete capabilities. It is not easy to miss there are two flexible pipes connected on the sensor body. New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube. 2020 Ram 3500, CM SK flat bed. I suppose we could compare notes and perhaps get a baseline from newer vehicles but probably the best thing to do (if the vehicle is otherwise running normally) would to be to just look for any significant negative changes or trends over time. Aftertreatment 1 Diesel Particulate Filter Differential Pressure - Data Valid But Above Normal Operating Range - Most Severe Level. I would always suggest to use a tool such as Cummins Insite or TEXA (you can even rent one from Diesel Laptops). If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. The exhaust backpressure will build and with nowhere to go can end up back in the combustion chamber causing the soot to mix with the engine oil.
