DPFs (diesel particulate filters) and sensors are a great concept. They take out the dangerously small carbon nanoparticles that diesel engines are so good at pumping out the exhaust port. Ideally, a DPF needs no maintenance, however, it must be cleaned thoroughly and replaced with new ones in time.

A DPF is just a steel chamber up near the engine full of Cordierite or silicon carbide designed to trap microscopic soot, and then periodically the system turns the chamber into a furnace by injecting extra fuel, thus burning the particles into a less harmful state.

So it is important to make sure that you take good care of both your DPF and Cummins differential pressure sensor to ensure long-lasting life for your vehicles.

So how do we do this?
