NOx sensor can be used for on-board diagnosis (OBD) (gasoline and diesel engines), rare-combustion engines (NOx defects), and diesel engines (NOx closed-loop control in SCR systems).

Accurately measure the nitrogen oxide (NO and NO2 nitrogen oxide mixture) concentration and oxygen concentration in the engine exhaust to meet the requirements of the closed-loop control of the engine post-processing system and the on-board OBD diagnostic system.
