When the injector is activated outlet nox should drop at least 70%. Remove the outlet nox sensor. Review the tables below to determine which category the fault code currently being diagnosed falls under. This code sets when the aftertreatment control module (acm) detects poor selective catalyst reduction (scr) nox conversion. Web 3 months ago had nox sensor replaced by freightliner.

Remove the outlet nox sensor. I haven't checked what the numbers are when driving. Replace the outlet nox sensor. Web this measurement happens between your inlet and outlet nox sensors and it’s called your scr nox efficiency. Web scr nox conversion measures the efficiency of this process, calculated by the engine control module (ecm) via inlet and outlet nox sensor.

Inlet And Outlet Nox Sensor Readings - Web the nox sensor is responsible for measuring the vehicles’ nox levels produced following the combustion cycle. 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%. Truck (dd13) has been running great since. I'm not really sure what the numbers are supposed to be, but it seems ok. Most of the time when a nox sensor fails it will have a code that reads “circuit high” or “circuit open” and it will also designate either inlet or outlet nox sensor to assist in. The primary failure mode the nox sensors is internal failure, which will generate a sensor specific fault code.

I'm not really sure what the numbers are supposed to be, but it seems ok. Web with no def doser operation both inlet and outlet should read close to each other. Web are the inlet nox sensor and the outlet nox sensor readings within 50 parts per million (ppm) of each other? Web 3 months ago had nox sensor replaced by freightliner who said my one box filters were due a cleaning, had dpfs baked overnight and doc filter blown out. Based on this, the ecu determines how much def the doser should inject into the exhaust gas.

Web Inlet And Outlet Nox Sensors.

Remove the outlet nox sensor. Web the engine control module compares the inlet and outlet nox readings to evaluate the efficiency of the scr. High conversion rates signify effective emission reduction, while low rates indicate issues needing attention. This fault code sets when the aftertreatment control module (acm) detects that the nox conversion is lower than a calibrated threshold.
