Walker Products - Genuine OE NOx Sensors. A NOx sensor holds a crucial role within emission control systems in vehicles featuring spark ignition (gasoline) and compression ignition (diesel) engines. It serves to monitor emissions of nitrogen monoxide (NO), nitrogen dioxide (NO2), and nitrous oxide (N2O, colloquially known as "laughing gas"), conveying data to the Engine Control Module (ECM). This information prompts adjustments to the engine's combustion process and emission control mechanisms, effectively curbing the release of these pollutants. By facilitating targeted emission reduction, NOx sensors contribute significantly to environmental preservation and regulatory compliance across a range of engine types.

By monitoring and adjusting air-fuel ratios, NOx sensors help engines operate at optimal levels, enhancing fuel efficiency and lowering consumption.
