\u00a9 2023 wikiHow, Inc. All rights reserved. Frank Mc, have you gone ahead with the dpf delete? This leftover diesel fuel can wash away the oil film that protects internal engine components and can cause catastrophic failure. General DPF faults: 2754, 3133, 3134, 3135, 3316, 3317, 3318, 3319, 3321, 3322, 3396, 5383 That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. Here's how to test the DPF. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. To find which wires are being used for each signal in your car, consult the manual. You could also create a free QuickServe Online Account to access all Cummins manuals and wiring diagram for your engine. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. I would think if it was not burnt and had good contacts it should be just fine but instead so many guys just change it out ! Bimmerpost Model Selection. i also removed the hydrocarbon doser and cleaned that, along with cleaning the imap sensor, cleaning the egr differential ports and sensor, the exhaust back pressure sensor, and even replaced the exhaust pressure . whether or not its possible id definitely appreciate any help as i dont know about resistors and would definitely like to try this out was thinking of wiring up something to a set of switches that when flipped it will progressively fool the sensor into thinking the filter is actively cleaning or becoming blocked. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi. They should not be damaged or plugged. Check for EGR differential pressure sensor blockage. JavaScript is disabled. 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. I don't see anything in the factory service manual that describes what the values should be. TROUBLESHOOTING: Check for other fault codes, if codes 3609/3 or 3609/4 are present. Remove Fuel with a large percentage of sulfur will clog the DPF faster. 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. Hi I got the autel 802 code reader and it gives exhaust back pressure and DPF differential pressure. Necessary cookies are absolutely essential for the website to function properly. Otherwise, you can remove the sensor and test the electrical resistance between the ports. As implied by the name, it is responsible for continuously detecting the pressure difference between exhaust gases before and after the particulate filter. You can buy multimeters online or from your local hardware store. <>/Font<>/Pattern<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> Spare Mini in my closet. Category: Exhaust Pressure Sensor / DPF Sensor. He has more than three years of experience writing for and working with wikiHow. use a multimeter and vacuum pump to test the pressure and voltage readings. This filter traps particulate matter (also called "soot") created by the engine. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. Although a three tenths of a PSI doesn't sound like much, I still wonder if there . In theory, theory and practice are the same. If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. New OEM Genuine Cummins Temperature Sensor 4954574. As I increase rpm to 2000 rpm (parked), back pressure increases to approximately 2000 hpa, and differential . 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. Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 Mopar DPF Pressure Differential Sensor 07.5-12 Cummins $361.81 Add to Cart Buy Now Ask Question Mopar 68453737AA Mopar MAP (Manifold Absolute Pressure) Sensor 07.5-18 Cummins $192.85 Add to Cart Buy Now Ask Question Cummins 2897333NX 07.5-20 6.7L Dodge Cummins MAP Sensor $98.76 Add to Cart Buy Now Ask Question Interstate-McBee M-2897333 4.6 V depending on differential pressure. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. If they are blocked or need cleaning, remove the 3 plugs (underneath the mounting position of the sensor) to gain access to the drillings. 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. The DPF differential pressure sensor can stop signaling to the PCM for regeneration. P2454 GMC Diesel Particulate Filter Differential Pressure Sensor Circuit Low Voltage. Thank you in advance for your support! While the engine is running you will then need to remove the hoses from the sensor. Has this been figured out, I'm almost due for a test and not interested in finding and swapping out the exhaust. 888.99.DIESEL. 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 replacement sensors from auto parts stores and they usually cost around $100150 USD.
