FAQ

Q1: Are A0111535128 and SNS1023 the same sensor?
A1: Yes. A0111535128 is the Mercedes-Benz OE number, and SNS1023 is the Continental/Vitesco reference used for the same NOx sensor module in SCR systems.

Q2: What vehicles use this sensor?
A2: It is mainly used on Mercedes-Benz Actros, Antos, and Arocs trucks, as well as Freightliner Cascadia models equipped with Detroit DD13/DD15/DD16 engines using SCR (AdBlue) systems.

Q3: Is this inlet or outlet sensor?
A3: It can be used as either inlet or outlet depending on SCR configuration. Heavy-duty Mercedes/Detroit systems often use identical NOx sensor types in multiple positions.

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