(888) 312-8812 Login SignupSensor, Nitrogen Oxide 4326874RX
The Cummins Nitrogen Oxide Sensor measures nitrogen oxides in the exhaust of ISX15 and ISX 11.9 engines so the aftertreatment system can confirm the SCR catalyst is doing its work. This outlet-side sensor reports to the engine controller, which uses the reading to manage DEF dosing and emissions compliance. The Cummins 4326874RX is a Cummins ReCon remanufactured unit, supplied as an exchange part. A healthy sensor clears NOx-related fault codes and helps the truck avoid the power derates that follow an emissions fault.
