WebNov 27, 2024 · How Does A Diesel Particulate Filter Work? A DPF system works sitting in between the vehicle engine and exhaust system. It’s a small to medium sized filter which catches exhaust soot and then stores it in the filter instead of it being pumped out of the exhaust and into the atmosphere. WebMar 9, 2024 · Here is a more detailed list of the signs of a bad or clogged diesel particulate filter (DPF) to look for: 1. Check Engine Light. The first, and most common sign of a bad DPF is a check engine light on your dashboard. The diesel particulate filter uses sensors to measure the pressure and temperature before and after the DPF filter.
