Dorman 904-943 Nitrogen Oxide (NOx) Sensor - Downstream or Upstream
Dorman NOx Sensor for Mercedes-Benz Diesel Applications
Dorman 904-943 is a specific-fit nitrogen oxide (NOx) sensor built to match the original equipment sensor on select Mercedes-Benz diesel vehicles. It restores NOx detection for emissions system monitoring and helps support compliance on covered Sprinter, GLS350d, GL350, and GLE300d applications.
- Specific-fit NOx sensor for select Mercedes-Benz diesel models
- Matches OE sensor form and function for emissions monitoring
- Black connector with oval shape and 5 terminals
- Wire harness included; 29-inch harness length
- 18-gauge wiring with blade-style terminals
- Black and silver finish
- Fits upstream and downstream positions depending on application
OE-Style Emissions Sensor Replacement
This Dorman nitrogen oxide sensor is engineered for direct replacement on covered Mercedes-Benz diesel applications, including 2013-2018 Mercedes-Benz Sprinter, 2013-2018 Mercedes-Benz Sprinter 2500, 2013-2018 Mercedes-Benz Sprinter 3500, 2018 Mercedes-Benz Sprinter 3500XD, 2017 Mercedes-Benz GLS350d, 2016 Mercedes-Benz GL350, and 2016 Mercedes-Benz GLE300d. It is also listed for 2010-2012 Mercedes-Benz Sprinter, Sprinter 2500, and Sprinter 3500 after Emissions Campaign Bulletin 2020040008 has been completed by a certified dealer. Part number 904-943 is a practical OE-style replacement when the original NOx sensor has failed or is no longer reading correctly.
This part cross-references Mercedes-Benz OE numbers such as 0009052809 and A0009058511 for the same application.
What This Sensor Helps Address
- Check engine lights related to NOx sensor performance
- Incorrect nitrogen oxide readings in the emissions system
- Emissions compliance issues on supported Mercedes-Benz diesel vehicles
- Fault codes tied to upstream or downstream NOx monitoring
- Driveability concerns caused by emissions system faults
Installation Notes and Tips
Verify the sensor position before installation, since fitment includes both upstream and downstream applications depending on the vehicle. Confirm the connector style, harness length, and OE part number match the original unit before replacement. For 2010-2012 Sprinter applications, confirm the emissions campaign bulletin requirement has been completed by a certified dealer before ordering or installing Dorman 904-943.
Quality Assurance
Dorman manufactures this NOx sensor to match the original equipment design on specified vehicles, helping ensure proper fit and emissions-system function. The part is built for specific applications rather than universal use, which supports accurate replacement on the listed Mercedes-Benz diesel models.
