Wrap Up. A Peterbilt derate happens because of numerous reasons. It could be due to the emissions system, or the DPF and SCR catalyst efficiency errors. When these problems arise, an engine derate occurs. For issues linked with emissions, the vehicle is likely to get into a 5 PMH derate enabled by your ECU.

Engine derate can be caused by a number of specific faults, most of which relate to a truck’s emissions system. Some of the most common of these issues include DEF quality and DPF/SCR catalyst efficiency faults. In general, faults of this type impede upon a truck’s ability to successfully complete its automatic regeneration cycle.The SCR/DEF system was implemented in Volvo Trucks 2011+ to curb exhaust emissions on Class 8 trucks.
