Walker Products 285-1009 nitrogen oxide (nox) sensor for the 2020-2024 Ford F-250 Super Duty V8 6.7L and other vehicles measures nitrogen oxide in the exhaust for the ECM. It is a downstream sensor that helps the ECM control emissions, including in selective catalytic reduction (SCR) systems.
- Sensing technology made for consistent NOx detection in extreme conditions
- NOx readings that help the SCR system run efficiently and lower emissions
- Made by Tier 1 suppliers with the materials and standards leading vehicle manufacturers use
- Fleet-tested in commercial and diesel use, in extreme heat, vibration and corrosive exhaust
- Plug-and-play design with a five-terminal, oblong gray connector
