Nox sensors for vehicles of the brand AUDI A4 are used to detect nitrogen gases in hot exhaust gases. The principle of the operation of the NOX sensor consists in dividing the exhaust gas into nitrogen and oxygen by a catalytically active electrode. The amount of oxygen is measured in the same way like at a broadband or linear lambda sensor.
