My experience: Single most important thing a Sprinter Owner can do is avoid interrupting DPF regenerations. Three DPF interruptions will throw a check engine light that may self-extinguish if highway operated for extended period of time, up to as much as 2 to 3 hours, interspersed with some stop and go driving, key cycles. • Check air filter (= conforms to manufacturer’s maintenance schedule) • Check fuel filter (= conforms to manufacturer’s maintenance schedule) • Check turbo performance (correct boost pressure is necessary for regeneration) • Check DPF pressure pipes are free from blockages • Check exhaust and boost pressure sensors The diesel particulate filter pressure sensor measures the exhaust back pressure of the gasses entering and exiting the DPF. An exhaust pressure condition or DPF pressure sensor signal that exceeds the limitations programmed will cause the PCM to log a P2452 code and illuminate the check engine light to warn the driver that something went wrong with the pressure sensor. Odd Odors: When your filter is packed with debris, exhaust gasses have no place to go. This builds up and creates odd odors. Not only is this unpleasant to breathe, but it can also cause a fire hazard for you. Check Engine Light: When you have a clogged DPF filter, your dashboard might give you the first clue. Sensors in your truck can detect a Truck has SPN 3720 FMI 16- DPF End of service life, need to replace your DPF filter. How to Fix-Replace / Clean DPF filter and use OTR Reset Tool to reset this fault from active to permanent (inactive). Truck has SPN 3719 FMI 0 - DPF Filter Soot Level Very High - DPF Zone 4/5 How to Fix-Replace / Clean DPF filter and use OTR Reset Tool to reset We’ve heard of a faulty temperature sensor on this model Triton that can lead the DPF to offer up a false alarm that it’s ready for a regeneration. That could explain the high number of regenerations the vehicle has demanded. Again, a scan might tell the full story.
Abstract: The accumulation of ash in diesel particulate filters is an important factor limiting the filter’s service life, increasing its pressure drop and having an adverse effect on fuel economy. The main sources of ash are engine lube oil additives, as well as fuels and engine wear and corrosion. A number of studies have been conducted and
