Maybe your aftermarket downstream sensor is bad. 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? The diesel tech i spoke with said it is very uncommon for a sensor to fail so.

Nox Sensor Ppm Readings - Diesel nox sensor technology | search autoparts. Web once the nox sensor is warmed up and giving an actual reading it should be anywhere between 0 and 200/300.the scr performance test is under the ecm diagnostic test tab. Maybe your aftermarket downstream sensor is bad. With no def doser operation both inlet and outlet should read close to each other. (as an example the upstream nox ppm should be near 100ppm when the downstream nox sensor 2 is around 30ppm or less). Additionally these sensors are not operational until the exhaust is up to operating temperature and free of moisture. Have you tried cleaning the old sensor and seeing if it works? Most engines feature two nox sensors: After the regen was finished. It never gives a reading and throws the fault code.

If it's not there you may need to update insite. Selective catalyst reduction (scr) inlet nox sensor, scr outlet nox sensor. (as an example the upstream nox ppm should be near 100ppm when the downstream nox sensor 2 is around 30ppm or less). Web in this paper, we investigate nox sensor reading correction in diesel engine selective catalytic reduction (scr) system applications. Maybe your aftermarket downstream sensor is bad.
