Sep 17, 2019 · Fault codes associated with Selective Catalyst Reduction (SCR) NOx efficiency low are the most dreaded codes you will find on the Detroit diesel application and can drive your costs high. Long story short, these fault codes mean that the efficiency in the aftertreatment system, aka the 1-Box, is not operating within the required threshold (70%). The HC-SCR uses HC as a reductant agent. However, in spite of its advantages, namely no NH3 dosing, low material cost [12], and systemic simplicity, HC-SCR could not be chosen for diesel NOx reduction because of its low NOx conversion efficiency at low temperatures [12].
