I just installed Car Scanner Pro app on my phone to monitor and display engine parameters.
I am trying to figure out which of the available sensors is the one to look at to understand where the DPF is at and when a regen might be ready to start.
The relevant ones I can find are: DPF delta pressure, DPF inlet pressure, and DPF outlet pressure. All in psi units. I also see a "DPF load % to regen" not sure what that is telling me.
Any ideas?
In the past I have not bothered with DPF regens at all, just let them happen and I motor on. I can always tell when one is happening by looking at EGT (bank 1 sensor 1) or NOx absorber Regen status (on or off), or listening for fans at a stop light or after I shut the engine off.
