2872944RX | Genuine OEM Cummins Nitrogen Oxide Sensor

2872944RX Genuine OEM Cummins Nitrogen Oxide Sensor is designed to measure nitrogen oxide (NOx) levels in compatible diesel engine exhaust systems. It provides emissions-related data to support exhaust aftertreatment monitoring and emissions control. The exact application should be verified using the original part number and engine specifications.

PRODUCT INFORMATION

Part Number: 2872944RX
Brand: Cummins
Condition: Genuine OEM
Component: Nitrogen Oxide (NOx) Sensor
Fuel Type: Diesel
Engine Applications: Not specified
Other important specifications: Exhaust emissions monitoring component

APPLICATIONS

The 2872944RX Cummins Nitrogen Oxide Sensor is intended for compatible Cummins diesel engine exhaust aftertreatment systems requiring this specific sensor. Exact applications may vary depending on the engine model, emissions system, vehicle configuration, and production specifications. Verify compatibility using the original part number and vehicle information before purchasing.

FUNCTION

The Nitrogen Oxide Sensor measures NOx levels in exhaust gases and provides data to the engine or aftertreatment control system. This information helps monitor emissions performance and supports the operation of compatible emissions control systems, including selective catalytic reduction (SCR), where equipped.

A worn, damaged, or failing Nitrogen Oxide Sensor may cause symptoms such as:

• Check engine warning light
• NOx sensor-related diagnostic trouble codes
• Exhaust aftertreatment system warnings
• Incorrect NOx readings
• Reduced emissions control performance
• Engine derate or warning messages, depending on the vehicle system

WHY REPLACE A NITROGEN OXIDE SENSOR?

A faulty Nitrogen Oxide Sensor may provide inaccurate readings or fail to communicate emissions data correctly. This can interfere with aftertreatment monitoring, trigger diagnostic trouble codes, and affect emissions system performance. Replacing a defective sensor with the correct Genuine OEM Cummins Nitrogen Oxide Sensor can help restore accurate NOx monitoring and support proper operation of the compatible emissions control system.

FITMENT INFORMATION

Before purchasing, verify the Part Number, VIN, vehicle model, engine, and configuration to confirm the correct application. Nitrogen Oxide Sensor compatibility may vary by engine family, emissions standard, sensor position, and aftertreatment configuration. Do not assume compatibility based only on the appearance of the part.

If you are unsure whether this part is correct for your vehicle, please contact us with your VIN and original part number. We are happy to help verify compatibility before purchase.
