Abstract
An apparatus includes an engine output module that determines an engine output power parameter for an engine. The apparatus includes an output power threshold module that determines if the engine output power parameter is below an output power threshold. The apparatus includes a NOx module that determines a nitrogen oxide ('NOx') efficiency of a selective catalytic reduction ('SCR') system in response to the output power threshold module determining that the determined engine output power parameter is below the output power threshold. The SCR system is in exhaust receiving communication with the engine. The apparatus includes a NOthreshold module that determines if the NOefficiency is below a NOefficiency threshold, and a NOwarning module that sends a NOalarm signal in response to the NOthreshold module determining that the NOefficiency is below the NOefficiency threshold.
