What Are Nox Sensors?
As the name implies, Nox sensors are components used in measuring and calculating the amount of nitrogen oxides in the exhaust gas. SCR systems contain a NOx sensor, which monitors the amount of nitrogen oxides being released into the air by a vehicle. If too much NOx is detected, the sensor will feed this information to the SCR system, which can then adjust its output accordingly so that the vehicle continues to meet emissions regulations.the NOx sensor is critical to the SCR system to ensure your vehicle is compliant.
