FAQ

Q1: Are A0101531928 and 5WK97341A the same sensor?
A1: Yes. A0101531928 is the Mercedes-Benz OE number, and 5WK97341A is the corresponding NOx sensor reference used in SCR diesel emissions systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Mercedes-Benz Actros, Arocs, and Antos trucks equipped with Euro 6 SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either upstream or downstream NOx sensor depending on exhaust configuration in the SCR system.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) levels in exhaust gases and sends real-time data to the ECU, which controls AdBlue dosing to reduce emissions and maintain SCR efficiency.
