All of the temperatures pressure dosing quantity correct,the whole system removed from the truck and cleaned. Even a DEF tank flushed and refilled. It to the regen starts normally low PPM on the outlet 80% efficiency and then it slowly goes down to 0 and that's it,truck keep regen and it never stops.

walmart pharmacy hours emporia ks Nov 1, 2019 · SCR NOx Conversion Efficiency Low. SPN 4364/FMI 18. DescriptionThis Code Sets When the Aftertreatment Control Module (ACM) detects That the Selective Catalyst Reduction (SCR) NOx Conversion Efficiency is Low. Monitored ParameterSCR Inlet NOx Sensor and SCR Outlet NOx Sensor 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 temperatures what happened to anaridis rodriguezo'reilly's on waters avenue After replacing those parts the SCR conversion code popped up only and then we replaced the Inlet NOX sensor.
