Product Overview

The 4326870 is a genuine Cummins Nox Nitrogen Oxide Sensor designed for EPA13 15-liter ISX/QSX engine applications. This sensor operates within the exhaust aftertreatment system by measuring nitrogen oxide levels and sending data to the engine control module for SCR, DEF, and EGR control. 

Product Features

The 4326870 Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for exhaust emissions monitoring.

  • Detects NOx concentration from exhaust flow so the ECM can evaluate aftertreatment operation.
  • Supplies sensor feedback used by SCR controls to manage exhaust emissions response.
  • Provides input required for DEF dosing calculations within the aftertreatment system.
  • Supports emissions logic tied to EGR operation and exhaust gas control.
  • Helps the ECM recognize abnormal NOx readings and related system faults.
  • Works with factory emissions wiring and control strategy for proper signal communication.
  • Intended for Cummins diesel exhaust aftertreatment systems that require NOx level monitoring.
