NOx sensors monitor Nitrogen Oxide levels in exhaust systems. Two sensors are typically used, one upstream and one downstream to assess Selective Catalytic Reduction System SCR efficiency. The ECU uses the readings to regulate DEF injection. Inferior sensors result in problems like weak acceleration, idling jitter, combustion issues, or failure to start. Choose OE quality sensors to avoid these complications.
