Product Overview

The 5WK96749B is a genuine Cummins Nox Nitrogen Oxide Sensor designed for EPA13 ISX/QSX 15-liter engine applications. This Nox Nitrogen Oxide Sensor operates within the exhaust emissions control system by measuring nitrogen oxide levels in the exhaust stream and transmitting data to the engine control module for SCR, DEF, and EGR system management. 

Product Features

The 5WK96749B Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for exhaust emissions monitoring.

  • Measures nitrogen oxide concentration in the exhaust stream for continuous emissions monitoring.
  • Provides real-time sensor feedback used by the ECM to manage exhaust after-treatment functions.
  • Supplies data that supports SCR system operation during emissions control.
  • Assists DEF dosing control by monitoring exhaust gas conditions.
  • Supports EGR system management through accurate NOx measurement.
  • Enables the ECM to detect emissions system faults when NOx readings fall outside expected values.
