It’s used as a means of keeping nitrogen oxides (NOx) and hydrocarbon emissions down, and it does so by diluting the amount of fresh oxygen making its way into the combustion chamber with cooled exhaust gases. A Nox sensor is very similar to a lambda probe, but its dedicated to measuring oxides of nitrogen in the exhaust gas. LNT) is a device that is used to reduce oxides of nitrogen (NO and NO2) emissions from a lean burn internal combustion engine by means of adsorption. 13 litre, in-line 4 cylinder - 105, 129 & 160 kW EU Stage IV / US EPA Tier 4 Final. The contamination may cause the nox se. From what I hear/read, most poor quality def problems are a bad NOx sensor ( ECM doesn't think def is changing NOx enough). Could be a shitty def injector, bad nox sensor, semi frozen fluid if it was anywhere near 20*, or there's a very slim chance it actually has poor quality def fluid. The injector verifies its own operation and can report a fault code if it is not working properlyas can the NOx sensor. " What all can this affect? and where is it located?. The NOx sensor cannot distinguish between NOx and liquid NH3 (DEF). Shop Cat® Parts Store online. The floor console fuse. We've been paying around $275 for a #9 injector. 2001-2004 GM 6.
