Most of the time it is a bad nox sensor. it can also be a bad scr injector, bad urea, urea crystals in the decomp tube, wrecked SCR, bad dosing pump/plugged filter, or a leak in the urea system. force a regen and compare inlet to outlet nox - when the scr is dosing the outlet nox should be much lower than the inlet nox (outlet should run about 25ppm).
