It is an electronic component that precisely injects DEF into the Selective Catalytic Reduction (SCR) system of a heavy-duty diesel engine. The metering unit controls the flow and atomization of the fluid, which helps break down harmful nitrogen oxide (NOx) emissions into harmless nitrogen and water vapor. These units are typically replaced when they fail due to crystallization buildup from the DEF fluid, electrical faults, or internal clogging, which can cause derate or fault codes on the truck.
