DEF derate or an aftertreatment derate

A derate means that the program inside the engine computer limits either the power or vehicle speed. A derate is designed to protect you from causing engine or DPF damage. A derate can be caused by various sensors or systems. However, when it’s a specific 5 MPH derate then you can be certain that the problem is related to the emissions, aka the aftertreatment system.
