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. $125.00. They worked, but I had the CEL. We changed B28/8 sensor, check cables resistance to ECU = 0,7 OHMS all three cables, and check the two small tubes to dpf for leaking all good like new, made two regeneration and mark in Xentry as DPF has been renew and still problem come on after 50 km or less. thanks, Frank. the difference between the two measuring points. Frank Mc, have you gone ahead with the dpf delete? Part NO. Is my DPF stuffed? | Ross-Tech Forums As I increase rpm to 2000 rpm (parked), back pressure increases to approximately 2000 hpa, and differential . If not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . I have same scanner and love it. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Piss!!!!!!! During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. This article was co-authored by wikiHow staff writer. if so do you have any ideas as to what sensors can be manipulated manually in order to control (activate and deactivate/complete) a regen? I wish that would have been stated in the instructions from PPEI when I did the delete. 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. Diesel Particulate Filter Diagnostics Using Correlation and Spectral CUMMINS DPF Differential Pressure Sensor 287196. These cookies ensure basic functionalities and security features of the website, anonymously. OE / OEM NUMBER. The two pipes allow exhaust gas pressure from the inlet and outlet of the DPF respectively to reach the sensor. for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? A standard pressure . The online store you use should provide you with access to industry experts to help you if you run into an unexpected problem changing the sensor. 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. 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?

How does a DPF pressure sensor work? Steps. P2453 - Diesel Particulate Filter Pressure Sensor "A" Circuit Range DPF-R will do the trick used one for about 8000 miles with no problem. While the engine is running you will then need to remove the hoses from the sensor. Finally, if youre looking to save money over OEM prices, consider an aftermarket DPF pressure sensor from a company based in North America. The ECM activates the STOP ENGINE lamp immediately after a DPF differential pressure fault is determined to be active. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. % of people told us that this article helped them. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. P2454 Chevrolet Diesel Particulate Filter Differential Pressure Sensor Circuit Low Voltage. The ECM constantly monitors the soot load of the DPF. Wiring harness: Incorrect wiring harness pin installation. 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. We use cookies to make wikiHow great. We know the equipment AND service end of the emissions industry! 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. If the soot load is high, a higher pressure difference is observed, because the accumulated soot will provide a restriction to flow on the DPF inlet side (Inlet pressure > Outlet pressure). . The sensor is located on the Aftertreatment system, mounted directly on the DPF.

Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. The DPF differential pressure sensor (DPS) has two pressure sample lines. The multimeter should normally display a voltage between 4.5 to 5 volts for referencing the 5-volt, a solid 0 volts for the ground wire, and anywhere between 0.5 and 4.5 volts for the signal wire. If the aftertreatment DPF differential pressure sensor signal voltage does n o t meet specification, replace the aftertreatment DPF differential pressure sensor. EGR differential pressure faults: 1866, 2273, 2274. endobj Some of the add-ons on this site are powered by. Make sure the battery voltage is about 12.6 volts. Page 3 AS, S.L.U. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi.

PDF Differential Pressure as a Measure of Particulate Matter Emissions from If the DPF has already been replaced during the repair (eg. My specialization is diesel engines and electronic management systems. 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. Also Mike, I do not idle it very long at all .
