NOx Sensor

The NOx sensor (Nitrogen Oxide sensor) is a critical component in modern diesel and petrol engine exhaust systems. It measures the concentration of nitrogen oxides (NOx) in the exhaust gases and transmits this data to the engine control unit (ECU). The ECU then adjusts the air-fuel ratio and the exhaust after-treatment system (such as SCR – Selective Catalytic Reduction) to ensure emissions compliance and optimal combustion efficiency. A malfunctioning NOx sensor can trigger the check engine light, reduce performance, and increase fuel consumption.
