A NOx sensor is a device designed to detect and measure the presence of nitrogen oxides (NOx) in the environment. NOx are chemical compounds consisting of nitrogen oxides (NO) and nitrogen dioxide (NO2), which are produced primarily during the combustion process.

NOx sensors are widely used in the automotive industry to monitor vehicle emissions. They detect the amount of NOx present in vehicle exhaust gases and provide useful information for emissions control and air quality monitoring.

NOx sensors can be of various types, but the basic principle typically involves the use of chemicals or electrochemical cells that react with NOx in the environment. The chemical reaction generates an electrical signal proportional to the NOx concentration, which can be measured and converted into a numerical reading or displayed on a screen.

NOx sensors are important for environmental monitoring and ensuring compliance with vehicle emissions regulations. They help identify air pollution situations and enable authorities to take appropriate measures to reduce the environmental impact of NOx-containing exhaust gases.

The AF sensor is also known as the NOx sensor control unit for emission control and is used before the catalytic converter (catalytic converter).
