An oxides of nitrogen sensor is used to monitor the levels of oxides of nitrogen that a vehicle emits to ensure it is compliant with emissions regulations.Controlling the levels of Nox emitted into the atmosphere is incredibly important, which makes the NOx sensor a vital vehicle component.
The Nox sensor is a key part of SCR system, which also includes the SCR catalyst, Diesel Particulate Filter (DPF), and turbocharger amongst others. If the NOx sensor detects too much Nox gases being emitted, it sends that information to the SCR system, which then adjusts the output to a level that's compliant with emission regulations.
