Product Overview

The 5WK9 6753 is a genuine Cummins Nox Nitrogen Oxide Sensor designed for Cummins diesel engine emissions system applications. This Nox Nitrogen Oxide Sensor measures nitrogen oxide concentration in the exhaust stream and transmits the information to the engine control module to support SCR, DEF, and EGR system operation.Β 

Product Features

The 5WK9 6753 Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for emissions monitoring and exhaust after-treatment system control.

  • Detects nitrogen oxide concentration directly from the exhaust stream during engine operation.
  • Delivers continuous sensor data that allows the ECM to manage emissions control strategies.
  • Provides the feedback required for SCR operation and DEF dosing adjustments.
  • Contributes to accurate emissions system diagnostics by reporting real-time NOx values.
  • Works alongside EGR and after-treatment components to support regulated exhaust emissions.
  • Designed for use across a wide range of Cummins electronic engine platforms listed in the supplied application data.

Installation Notes

The 5WK9 6753 should be installed in the designated exhaust sensor location with the connector fully engaged and the wiring harness inspected for heat damage, corrosion, or loose terminals. After installation, verify ECM communication and clear any stored NOx, SCR, or emissions-related diagnostic trouble codes if necessary.

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