If the scr nox efficiency goes below 70%, then these fault codes get set “active.” the only way you can clear these codes is by doing a forced regen with the scr nox efficiency above 70%. Information for the temperatures and nox sensors can be pulled from the dpf service regeneration and the reductant system malfunction warning service bay test from session files or stored data in gds2. Nox1 gets a reading, def injected, nox 2 gets a reading.
The affected emissions may include nox, pn, pm, hc, co, co 2 (fuel economy) as well as unregulated species such as hcho, nh 3 and so 2 [5608]. The egr system is designed to recirculate exhaust gases into the combustion chambers to reduce the nitrogen oxide (nox) emissions. Web the levels of emissions can increase substantially during dpf regeneration—especially during.
And the dealer says that the manual regen is chargeable to me. Nox inlet will be high of course and the outlet will be much much lower. If the nox2 reading is not low enough, more def is injected and if it can't keep nox 2 low enough it throws a code. This can be the result of a degraded.

If the scr nox efficiency goes.
Web the levels of emissions can increase substantially during dpf regeneration—especially during active regeneration events but also during stochastic regeneration in passive filters. Web ok, it may or may not come back during a regen. Web high nox sensor 2 readings can be caused by def getting past the scr catalyst. After the regen was finished. It never gives a.
Web ok, it may or may not come back during a regen. If the scr nox efficiency goes below 70%, then these fault codes get set “active.” the only way you can clear these codes is by doing a forced regen with the scr nox efficiency above 70%. The affected emissions may include nox, pn, pm, hc, co, co 2.
