Walker Products NOx (Nitrogen Oxide) Sensor P/N:1004-1030
Walker Products 1004-1032 nitrogen oxide (nox) sensor for the 2015-2024 Freightliner Cascadia and other vehicles measures nitrogen oxide in the exhaust stream.
A failing sensor can bring on an emissions warning light or related fault codes. These signs alone do not prove the sensor is the problem, since damaged wiring or a loose connector can cause them too. This listing is one sensor, and each application takes one at that spot.
This nitrogen oxide (nox) sensor also fits the 2021-2024 Western Star 49X 6-cylinder 11.9L, 14.8L or 15.6L, the 2022-2024 49X 6-cylinder 14.9L, the 2023-2024 49X 6-cylinder 12.8L and the 2015-2024 Freightliner 114SD. Open the "Vehicles it fits" section to check your exact model and engine.
