DPF problems: How diesel particle filters actually regenerate | Auto Expert John Cadogan Share Watch on Too much misinformation is being served up about how DPFs work and how they regenerate. It’s time to sort that out, here and now Mat, I have a 2008 ford 6.4l that will not start with codes 246c and 2463 dpf soot accumulation. Installed new dpf, reset dpf timer and cleared codes, in 15 miles of driving regen starts and codes com … read more DPF can accumulate and combust PM within the filter element to achieve greater than 85 percent reductions in PM emissions. The combustion of PM in a filter occurs during regeneration. During normal operation a DPF will cause fluctuations in exhaust backpressure as PM is accumulated. Consequently, a DPF is used in conjunction Once the cleaner is sprayed into the filter, wait for 10 minutes and then spray the entire bottle of Pro-Line Purge into the Diesel Particulate Filter, disturbing all the deposits. The last step is to use a scanner to do a manual regen to complete the cleaning process. Unfortunately, DPF filter cleaning with Liqui Moly is not a DIY kit. How the DPF Regeneration Process Works. The DPF is designed to capture soot particles over time. When the filter becomes too clogged, it needs to be "regenerated" in order for it to continue functioning properly and save your engine. Regeneration is a process where the pollutants are burned off in high-temperature exhaust gases. 2017+ Super Duty - DPF Filter % screen probs - Hey all, So i have had my 2019 F350 XLT 6.7 for a whopping 3 weeks now and i decide to add the DPF % screen to see when the system decides to do a regen. I used forscan and added the screen to the information center. However, after a day of driving, the % on the screen Dealership states that they ordered and will replace the Diesel Particulate Filter. I feel they are just grabbing at straws. On my truck, on the third replacement of the NO2 Position 2 sensor, the mechanic found an incorrectly assembled harness for that connector causing corrosion to simulate a failed sensor. The ECM uses the following criteria to perform a regeneration: Vehicle in Drive. BARO sensor 1 is more than 51 kPa (7.4 PSI) Engine speed between 500 and 4000 RPM. Exhaust Gas Temperature Sensor 1 between 100 and 725 C. Exhaust Gas Temperature Sensor 2 between 95 and 750 C. .
