It's important to rev the engine and check for voltage changes before testing anything else. Also check for pin-to-pin short circuits. Guys, my MD802 is telling me that the DPF is too clogged to regen so I'm assuming that it can only be cleaned by taking it out and manualy cleaning it , chemical or roding it out ?? 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. It's bad!!!!!! One line is attached before the DPF. I just watched an active regen on my 2007 2500. %

Replace the DPF. During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. 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). If the measured temperature difference is within specifications, proceed to the next step. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). DPFPartsDirect.com meets all these qualifications. O'Rileys Autos - Mobile Mechanic & DPF Cleaning 16.1K subscribers Subscribe 58K views 8 months ago diagnosing a diesel particulate filter differential pressure sensor 1: check voltage. % By using our site, you agree to our.

Engine misfire: 1654, 1655, 1656, 1657, 1658, 1659 The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. This keeps this site running and allows me to keep creating content. Free shipping. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi. In other words the higher the differential the faster it goes up the scale. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). 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. The whole system must work in close-knit harmony to deliver a reliable drive, time and again. i replaced the dpf with a cummins reman.
