General DPF faults: 2754, 3133, 3134, 3135, 3316, 3317, 3318, 3319, 3321, 3322, 3396, 5383 This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Cummins DPF Differential Pressure Sensor - 2871960. The 452A code is an information code only for BMW service to advise the customer that the DPF is approaching it's calculated end of life and they should make an appointment for a $4800 DPF replacement. Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 I disconnected the exhaust outlet and ran a snap test and found no smoke exiting the engine. 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). It does not store any personal data. Ended up finding a lot more information I wanted to learn. Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. TROUBLESHOOTING: Check for other fault codes, if codes 3609/3 or 3609/4 are present. The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. The sensor is located on the Aftertreatment system, mounted directly on the DPF. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash. Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational.

Connect your diagnostic tool and monitor the fault code page. Engine and DPF Sensor Signal Based Methods 13 2.3.1. Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). Although a three tenths of a PSI doesn't sound like much, I still wonder if there . <> 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 . 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. In practice, they are not. At one point it reports the charge status of the particle filter and monitors its function. These are signs that the DPF sensor is dying, and the DPF may not correctly regenerate. This helps determine if you need to clean or replace the filter to avoid clogs. The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. This diagnostic is typically Diesel Particulate Filter (DPF) Pressure Out of Range High. : WL-D05013. . New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube. Well I just replaced the DPF differential pressure sensor and cleared the codes, however two codes came back . The correct oil is hard to find and spendy . You will never receive any spam from me. 6 0 obj It's bad!!!!!! I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. 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. 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. Not if you can take control of the regen fuel map, it's there just have to find it, I can adjust it on engineering level insite on off road engines, can adjust the fueling value and the timing from almost less than a trickle to 2000* EGT temps.. now you're thinking! 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.

Fault codes 1879 and 3134 should become active. Noticed exhaust temp upstream of dpf was 650-750, then dropped to 350 after.

The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. 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. What is a DPF differential pressure sensor? If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. correctly. The ECM activates the STOP ENGINE lamp immediately after a DPF differential pressure fault is determined to be active. now are you positive resistors cant be used in the DPF sensor? Excessive ash in the DPF, causes blockages. Use channel exclusive promo code road3333 to get 12% off of your order today. Wiring harness: Incorrect wiring harness pin installation.
