Forced regen face plug question - DosGatos - 03-10-2019
Haven't done a forced regen (insite) since august. May have forgotten a few things. Had to reinstall insite after windows 10 update ( I know, I know...).
Anyway have the software running noticed two things; 1. Active faceplug fault from idling a lot, not surprised but assume I have to drive off the active fault before I can run a forced parked regen. 2. With key on engine not running, the dpf parameter for differential pressure reads 0.12. Any thing I can do to zero that out? Thanks
2009 engine year 871 dpf no scr 800k miles

Do a forced regen, and hopefully the hg reading will be far below 12

cleared the faceplug fault. did the regen and dpf differential after was 0.0 with key on engine not running with idling pressure of 0.2 after the cook. Not sure where the 0.12 was coming from earlier. history is typical; between 2 and 13 hours between rolling regens. depends on load weight and speed.
the maximum pressures during rolling regens may be while pulling a hill. the parked regen looks better but was only 1100 rpm no load.
satisfied considering the miles and hours; a little over 20k hrs run time. Was a mega fleet truck with company drivers.

maybe you got it solved. All but the newest (topmost value) numbers down the right hand side don't look too good. Above 3.0 inhg is not so good in history.

If I drive with the laptop running, I can see the doser on, temps and pressure. The "3's" are on hills at 1500+ rpm. Always been that way since I've had the truck. On flats I'll see 1.7 at 65mph 1450rpm.
