Walker Products NOx (Nitrogen Oxide) Sensor P/N:1004-1091
Walker Products 1004-1087 nitrogen oxide (nox) sensor for the 2017-2024 Freightliner M2 106 and other vehicles measures the nitrogen oxide level in the exhaust gas. It reports that reading to the engine control system.
An emissions warning light or a stored fault code can be a sign that the sensor is failing. Before you replace it, rule out damaged wiring, a loose connector and other emissions parts that can set the same code, and have a shop read the codes.
The 2017-2024 Freightliner M2 106, the 2019-2024 Freightliner B2 and the 2015-2024 Freightliner Cascadia are among the vehicles this sensor fits. The 2015-2024 Freightliner Cascadia takes one. For a different Freightliner model or engine code, look up your truck in the "Vehicles it fits" section.
