Description
Remanufactured Detroit Diesel inlet NOx sensor (RA0101531928) for the pre-SCR position in the DEF/SCR aftertreatment system on DD13, DD15, and DD16 engines. Reads nitrogen oxide concentration entering the catalyst so the engine controller can dose DEF accurately, hold emissions in compliance, and avoid derate. Core charge applies. New OEM is A0101531928; OEM exchange is EA0101531928; PAI offers an aftermarket alternative as 650625.
