🦭 Mazda 6 Dpf Regeneration Frequency

The P2459 Diagnostic Trouble Code (DTC), labeled as “Diesel Particulate Filter Regeneration Frequency,” is a generic code specifically relevant to vehicles equipped with diesel engines. When this code is triggered, it signifies that the powertrain control module (PCM) has identified issues related to the diesel particulate filter (DPF Paying attention to the frequency of a vehicle’s regeneration cycles is the most effective way to determine whether or not there has been significant ash buildup in its DPF. If they are ignored, the end result could be an irreversibly-damaged DPF that is cracked, glazed or melted. The Edge CTS dispays parameters that the PCM monitors. One of those is SOOT % Ford must have some sensor that measures the soot collected and triggers the regens when that concentration is reached. The 6.7 will do either a Passive Regen ( anytime you have exhaust heat over 572*) and the Active Regen when the percentage triggers it. 387 posts · Joined 2017. #23 · Feb 25, 2018 (Edited) The best and optimal way for dpf regeneration is to drive with a constant speed on 5 or 6 gear and keep it at around 2000-2500rpm max. Have a look into my thread for more info about DPF regeneration and how to monitor its frequency, here. The P2459 Ford will set if the Engine Control Module (ECM) detects that the average time between completed regenerations is less than a calibrated threshold. The particulates in the exhaust gases are collected by the Diesel Particulate Filter (DPF). When the filter becomes saturated with particulates, they are incinerated by a regeneration process.

So recently in the past few weeks I have been noticing odd regen frequency. They come and go throughout the day and what it looks like is the DPF soot load is not getting above 33%? Some times it doesn’t even get above 23%. Right now, I am driving a consistent 65 and it’ll raise to 23 and then drop back down to 17 to 19. Diesel particulate filters are an efficient means of reducing particulate emissions of diesel engines by orders of magnitude. The necessary periodical regeneration of these filter systems requires drastic changes in the engine management, notably in fuel and air path control, because the temperature levels required for regeneration are 200 vm9S.
