Dorman 904-6049 nitrogen oxide (nox) sensor for the 2013-2014 Ram 2500 6-cylinder 6.7L and other vehicles reads nitrogen oxide levels in the exhaust for the emissions system. It is reverse engineered to match the original equipment sensor on certain vehicle years, makes and models.
A check engine light or an emissions fault code can mean this sensor is worn, though a damaged wiring connector or another exhaust sensor can also be behind a code like that, so find the cause before replacing the sensor.
The vehicles it fits include the 2013-2014 Ram 2500 6-cylinder 6.7L, the 2013-2015 Ram 3500 6-cylinder 6.7L and the 2013-2015 Ram 4500 6-cylinder 6.7L. This listing is one downstream sensor, and each of them needs just one. If your vehicle is not named here, look for it in the "Vehicles it fits" section.

This part cross-references / interchanges with the following part numbers:
Is the Dorman 904-6049 NOx sensor right for the 2013-2014 Ram 2500 6-cylinder 6.7L?
Yes. Dorman 904-6049 is the downstream sensor for the 2013-2014 Ram 2500 6-cylinder 6.7L. For other models, look in the "Vehicles it fits" section.
Does this NOx sensor come with its module?
Yes. The package holds one sensor with module.
How long is the wiring harness on the Dorman 904-6049?
The harness on Dorman 904-6049 is 620 mm long. It ends in a black, female rounded-rectangle connector, and the sensor has four male blade terminals.
What can a worn downstream NOx sensor look like?
A check engine light or an emissions-related fault code can show up with a worn sensor. A shop can scan the codes and test the sensor.
Does 4N3002 interchange with this NOx sensor?
Yes. 4N3002 is one of the numbers this sensor replaces, along with 68085740AA and S11117.
