test cycles, they have poor NOx conversion efficiency when exhaust gas temperatures are low, such as during cold start, low-speed, low-load driving and during extended idling. This is because SCR performance is limited by urea decomposition issues at exhaust gas temperatures below 180°C. If urea is injected at exhaust gas temperaturesDiesel Exhaust Fluid (DEF) helps in converting harmful nitrogen oxides (NOx) into nitrogen (N2) carbon dioxide (CO2) and water. The powertrain control module (PCM) monitors the efficiency of the SCR catalyst using NOx sensors. If the SRC fails to efficiently perform its job, code P20EE will be logged.Unfortunately, the air/fuel ratio for which NOx conversion efficiency is high, corresponds to a very low conversion efficiency for HC and CO and vice versa.
