Troubleshooting: DESCRIPTION: Selective Catalytic Reduction (SCR) abnormal temperature rise. MONITORED PARAMETER: Diesel Particulate Filter (DPF) outlet temperature, SCR outlet temperature.Also problems within the aftertreatment system. It is more of a process of elimination. You need to have the system pressure/smoke tested or pressure tested at 2-20 psi. Once exhaust gets to the SCR there are 2 things that lower NOx, DEF through the Doser and the SCR catalyst. The SCR is like a catalytic converter on a car.
