Dorman Nitrogen Oxide (NOx) Sensor 904-6003

The NOx (Nitrogen oxide) sensor is a high-temperature sensor designed to detect NOx levels in diesel-fueled vehicles that must comply with state emissions regulations. As state emissions requirements become more demanding for diesel vehicles, it is imperative to have a quality sensor to notify the driver when high amounts of NOx levels are in the engine.
