FAQ

Q1: Are 5WK96665 and 21040930 the same sensor?
A1: Yes. 21040930 is the OE part number used by Volvo/Renault, and 5WK96665 is the corresponding NOx sensor reference used in SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Volvo FH, FM, FMX, FL, FE trucks and Renault heavy-duty vehicles equipped with Euro 5 / Euro 6 SCR (AdBlue) emissions systems.

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

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