The diesel particulate filter is the whipping boy of the heavy-duty truck aftertreatment system. It can be costly to replace as obvious culprit of fault codes … or maybe a little too obvious.

It’s there to capture the particles that weren’t burned up in the engine. So if you have particles clogging the DPF, causing fault codes and engine derate situations, you can replace the DPF all you want, but you won’t fix the problem.
