Dorman 904-6006 nox (nitrogen oxide) sensor for the 2013-2018 Freightliner M2 106 and other vehicles reads nitrogen oxide in the exhaust at the SCR catalyst outlet. It replaces a failed sensor and is intended to restore nitrogen oxide detection so the vehicle can meet emissions regulations.
- Designed to restore nitrogen oxide detection for emissions compliance
- Application-specific design, reverse engineered from the original design
- Supplied as a sensor with module
- 620 mm wiring harness with 20 gauge wire
- 4 male pin terminals and a female oval connector
Quick facts
- Part: Dorman 904-6006 nox (nitrogen oxide) sensor
- Fits: 2013-2018 Freightliner M2 106 and other vehicles
- Position: SCR catalyst outlet
- Condition: New
A failing NOx sensor can show up as a dash warning light or an emissions fault code, and damaged wiring can trigger those too. With the engine off and cool, look over the harness and connector for chafing, corrosion or bent pins before you buy a sensor; a shop can test the sensor itself.
Fits
It is listed for a wide range of Freightliner, Kenworth, Peterbilt and International models, starting with the 2013-2018 Freightliner M2 106 and the 2018-2021 Freightliner Cascadia. On those vehicles it matches the original sensor's function and performance as a direct replacement. Both take one sensor per vehicle, and this listing is a single sensor. If your truck, bus or motorhome is not named here, look it up in the “Vehicles it fits” section.
