The performance of the SCR is evaluated by the NOx sensors. There are NOx sensors that are located on upstream (inlet) and downstream (outlet) ends of the SCR. Important: the SCR is the last component in the EATS which makesKnowing this, it is easy to see why the SCR would be a common failure component. It will come into contact with any stress caused by both incoming power and output load issues. But for the same reasons, SCR's chosen in most motor control applications are picked to be able to withstand many times the drive and motor's rated capacity.When nothing is accomplished during this step, a red stop engine light will illuminate your panel, and the engine may eventually shut down or derate. Three Different Ways of Engine Derates As mentioned, engine derating is the method of altering an engine in a way that it will work at a reduced capacity compared to its actual pace.if you do nothing, the power will reduced at the engine by 25%. if you continue to do nothing, it will eventually allow only 5 mph speed. you need to have code identified and …so this kind of fault code scr efficiency is the most general fault you can think of anything from dpf being ready to clean and bake to the engine putting in to much smoke or not using enough egr will cause this kind of fault even bad injectors will, that being said this is not something that constantly gets monitored so all they are doing is reseting it and then you go 1000 miles and same ...Dd15 yellow def low level light is flashing def full.
