It delivers DEF from the tank to the vehicle's SCR (Selective Catalytic Reduction) system, where it is injected into the exhaust to reduce nitrogen oxide (NOx) emissions. The pump is powered by a 12/24V electrical system and is typically replaced when DEF pressure faults, crystallization, or SCR efficiency codes occur due to pump failure or clogging. Using the correct OEM pump helps maintain aftertreatment system reliability and avoids expensive ATS repairs.
