Product Overview

The 2872947 is a genuine Cummins Nox Nitrogen Oxide Sensor designed for Cummins diesel engine emissions system applications. This sensor measures nitrogen oxide levels in the exhaust stream and provides data to the engine control module for SCR, DEF, and EGR system control. 

Product Features

The 2872947 Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for exhaust emissions sensing and ECM feedback.

  • Reads exhaust gas NOx levels so the control module can track after-treatment conditions.
  • Provides emissions input used during SCR system operation.
  • Supports DEF/AdBlue dosing calculations through measured exhaust data.
  • Helps the ECM compare exhaust readings against programmed emissions limits.
  • Supplies data used when diagnosing NOx sensor, SCR, DEF, or emissions-related faults.
  • Fits multiple Cummins electronic engine control platforms listed in the supplied application data.

Installation Notes

The 2872947 should be installed in the correct exhaust sensor location with the connector locked in place and the harness checked for heat damage, corrosion, or loose terminals. Confirm ECM communication after installation and clear any active NOx, SCR, DEF, or emissions-related diagnostic codes before returning the equipment to service.

Verify part number, VIN, engine configuration, production date, emissions package, and applicable factory options before installation.
