Nox Sensor Readings During Regen - Additionally these sensors are not operational until the exhaust is up to operating temperature and free of moisture. Web this measurement happens between your inlet and outlet nox sensors and it’s called your scr nox efficiency. Web nox regen and sox regen use what's known as a rich mode where a/f ratio is tightly monitored and controlled using maf/o2 sensor readings (exactly like a gasser lambda control) during late post injection. There is one right after the exhaust manifold and the second after the selective catalytic reduction (scr) system to monitor scr efficiency. And the dealer says that the manual regen is chargeable to me. Web the following procedure is to aid in graphing nox sensor readings and temperature sensor readings using the gds2.
It never gives a reading and throws the fault code. Nox1 gets a reading, def injected, nox 2 gets a reading. Web obtain the barometric pressure reading for your area, compare your barometric pressure reading to the barometric pressure reading in diagnosticlink. Have you tried cleaning the old sensor and seeing if it works? Web high nox sensor 2 readings can be caused by def getting past the scr catalyst.
Web The Levels Of Emissions Can Increase Substantially During Dpf Regeneration—Especially During Active Regeneration Events But Also During Stochastic Regeneration In Passive Filters.
