FAQ

Q1: Are 9821120980 and SNS0736 the same sensor?
A1: Yes. 9821120980 is the PSA OE number, and SNS0736 is the corresponding NOx sensor reference used in Citroën / Peugeot SCR diesel systems.

Q2: What vehicles use this sensor?
A2: It is commonly used on Citroën and Peugeot diesel models such as Berlingo, C3, C4 Picasso, 208, 308, 3008, and 5008 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 layout and SCR 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 injection to reduce emissions and maintain SCR efficiency.
