Part number A0101531928 is an upstream (inlet) nitrogen oxide (NOx) sensor primarily used in heavy-duty Detroit Diesel (DD13, DD15, and DD16) and Mercedes-Benz engines. It plays a critical role in the Selective Catalytic Reduction (SCR) aftertreatment system by measuring exhaust emission levels before they enter the catalyst, allowing the engine control unit (ECU) to calculate the precise amount of diesel exhaust fluid (DEF) to inject.
Cross-Reference Numbers:
Continental/Continental-Siemens: 5WK9 7341A, 5WK97341A
Mercedes/Detroit Diesel: EA0101531928 (New Genuine)
Cross-Reference Numbers: RA0101531928 (Remanufactured), and A2C89603500
