Product Overview

The A044C669 is a genuine Cummins Nox Nitrogen Oxide Sensor designed for EPA13 8.9-liter ISC/ISL engine applications. This sensor operates within the exhaust aftertreatment system by measuring nitrogen oxide levels in the exhaust stream and sending data to the engine control module. 

Product Features

The A044C669 Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for exhaust emissions monitoring.

  • Measures nitrogen oxide levels directly from the exhaust stream.
  • Sends NOx readings to the engine control module for emissions control decisions.
  • Provides input used by the SCR system during aftertreatment operation.
  • Supports DEF dosing control through exhaust gas monitoring data.
  • Works with EGR-related control logic by reporting exhaust NOx levels.
  • Helps the ECM detect emissions faults related to NOx sensor signal behavior.
  • Designed for factory emissions wiring and aftertreatment system communication.
