\u00a9 2023 wikiHow, Inc. All rights reserved. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape. check wiring diagram). Black - Diesel DPF Particulate Filter Differential Pressure Sensor For 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. Keep your vehicle turned off while you remove the pressure sensor. +5 Volt supply, ECM Return, DPF outlet pressure signal, DPF differential pressure signal. one on each side of the DPF, and it takes a reading of the pressure differential between the two. References. If your signal values do not meet specifications, check once more to ensure you are doing this correctly. You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow. The sensor monitors and measures the pressure with the EGR valve. The sensor is located on the Aftertreatment system, mounted directly on the DPF. MBRP 4", 2012 Leather interior, still a work in progress this is all about EGT sims. im talking about one for the DPF sensor these egt sims will only prevent or prolong a regen. Thank you in advance for your support! This article has been viewed 45,868 times. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). Typical DPF Sensor readings | The Motorhome Fun Club. endobj The Pressure Differential Sensor on your 6.7L Cummins tells the ECM how "full" your DPF is. Hi I got the autel 802 code reader and it gives exhaust back pressure and DPF differential pressure. DPF differential pressure sensor signal stuck-in-range. We proudly carry Redline Emissions Products differential pressure sensors for many makes and models, and our parts meet or exceed OEM parameters. Lastly, check the signal voltage one last time. Differential Pressure Sensor (DPS) - Exhaust Pressure Sensor - RPF Pressure Sensor In the exhaust system of your vehicle, the differential pressure sensor measures the pressure upstream and downstream of the diesel particulate filter, i.e. The Fora platform includes forum software by XenForo. Sometimes the DPF is misdiagnosed as the problem and replaced only to quickly fail again because the sensor is the actual issue. 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 You can buy vacuum pumps online or from auto part stores. Product Introduction. Proceed to check the condition of the ports on the EGR mass mesurement flow assembly. If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. My specialization is diesel engines and electronic management systems. Wiring harness: Incorrect wiring harness pin installation. It is not easy to miss there are two flexible pipes connected on the sensor body. Check if the signal of the aftertreatment temperature sensors is within specifications. Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 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. Diagnose those codes first. In today's video, Ryan is showing you the dignosis of replacement of cummins ISX15 DPF differential pressure sensor on his Kenworth T660.Announcement WE ARE GOING TO MID-AMERICA TRUCKING SHOW2023 Mid-America Trucking Show: March 30 - April 1, 2023 - Kentucky Exposition Center- Louisville, KYThursday, March 30 - VIP Session: 10AM - 1PM, Show Hours: 1PM - 6PMFriday, March 31 - Show Hours: 10AM - 6PMSaturday, April 1 - Show Hours: 9AM - 4PMRegister today with our code: HJFZBLMeet with us at 2023 Mid-American Trucking ShowOur Truck Repair Shop: Fox Truck \u0026 Tractor LLC (Truck Maintenenace, Repair \u0026 Inspection) https://www.foxtruckandtractor.com/Our Diesel Emission Shop: Diesel Emissions Specialists LLC (DPF, DOC, SCR \u0026 Full One Box Cleaning, Sensor Bung Replacement, TIG/MIG Welding \u0026 General Repairs)https://www.emissionspecialists.com/Our Truck Parts Sales: Diesel Truck Parts Store ( All-makes line of aftertreatment emissions parts, (with over 100 SKUs for DPFs / DOCs, over 45 clamps, over 110 gaskets, over 100 sensors, over 45 weld bungs, and over 30 charge air coolers \u0026 accessories), Used \u0026 Open Box truck parts)EMAIL/CALL US TODAY TO ORDER YOUR AFTERMARKET EMISSION PARTS FOR VERY AFFORDABLE PRICE!! In theory, theory and practice are the same. This helps determine if you need to clean or replace the filter to avoid clogs.

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. Level up your tech skills and stay ahead of the curve. This cookie is set by GDPR Cookie Consent plugin. Where should you buy your replacement DPF sensor should it need to be replaced? Free shipping. A forum community dedicated to Dodge Cummins Diesel truck owners and enthusiasts. I'd strongly suggest getting either an "OBDLink" cable or Bluetooth device rather than trying to use an ELM327 device to connect Multiecuscan to your van, MES seems to have no end of issues with the cheap ELM units. Exhaust Gas Recirculation (EGR): 1228, 1896, 2272, 2349, 2353, 2357, 2961, 2962, 3136, 3137, 3138, 3342, 3382, 3383, 3389 These cookies track visitors across websites and collect information to provide customized ads. Here ya go, using the search function for this thread,, I have the three 100 OHM sims used for the DPF; Used very little until I went with EFI live, a couple of years ago. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Fired her up and instantly got totally different readings with no error codes. PDF Differential Pressure Sensors for DPF - EngineSens Connect your diagnostic tool and monitor the fault code page. What to Look For in a DPF Differential Pressure Sensor That is Failing . anyone know of what resistors can be used to fool the DPF sensor into thinking an active regen is working? Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . thanks, Frank. You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. 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. When the diesel particulate filter is not regenerating properly due to the faulty DPF sensor failing you may experience some of or all of the below symptoms: A DPF pressure sensor is necessary to keep the DPF free from diesel particulate matter and soot, and if the DPF is plugged, the regeneration process will not fix it. For a better experience, please enable JavaScript in your browser before proceeding. In other words the higher the differential the faster it goes up the scale. Is my DPF stuffed? | Ross-Tech Forums To replace it, simply remove the old one and replace it with the new one. Once you remove the guts from the DPF, you will end up with a check engine light and the engine will eventually go into De-Rate. DPF Differential Pressure Sensor - Consensus. Diesel Particulate Filter(DPF) Differential Pressure Sensor If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. 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? 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. Check out my diagnostic tool suggestions! 7.If needed, shorten the tubes to achieve a 0-10 degree sensor tube down angle.
