Nitrogen Oxide (NOX) Sensor - Downstream - 2019-2020 Dodge RAM 6.7L Cummins
Part # NX1089
A NOx (Nitrogen Oxide) sensor in a 6.7L Cummins diesel engine measures the amount of harmful nitrogen oxide gases in the exhaust. It provides crucial feedback to the engine computer (ECM) to ensure compliance with emissions regulations and to properly adjust the air-fuel mixture and DEF (Diesel Exhaust Fluid) dosing.
Most 6.7L Cummins engines have two NOx sensors working together to manage the Selective Catalytic Reduction (SCR) system.

Signs of a Failing Sensor
A malfunctioning or soot-covered NOx sensor can cause several drivability and efficiency issues:
- Decreased fuel efficiency.
- Abnormal or unexpectedly high DEF consumption.
- Rough engine performance, a check engine light, or the truck entering "limp mode".
- Visible dark smoke from the exhaust.
