Vast majority of those 3 bung cats have come in as failed in my experience. You have an updated , updated wiring harness for the SCR sensors that deletes the connector for the NH3 and an updated calibration so the ECM does not search for the NH3 sensor (will need a fleet cal and would have to be done at a dealer unless you got Insight pro and a quickserve log on).

The Danfoss IXA NOx, SO2 and NH3 sensor, MES 1001, helps you ensure . SCR performance and enables optimization of the SCR process. Selective Catalytic Reduction . The traditional approach to controlling Selective Catalytic Reduction (SCR) is by means of the engine load signal, where the amount of urea injected . into the SCR is controlled as a function of the load. An alternative and cost ...

If the scr still has the nh3 (midstream ammonia sensor) that scr is obsolete. There is an updated one with just the nox inlet and outlet sensors with a new wiring harness. Putting the new scr on has fixed the constant low scr conversion efficency codes.
