Product Overview

The 1954664PE is a genuine Cummins Nox Nitrogen Oxide Sensor designed for EPA13 ISX/QSX 15-liter engine applications. This Nox Nitrogen Oxide Sensor is part of the exhaust emissions control system, where it measures nitrogen oxide concentration in the exhaust stream and relays that information to the engine control module for SCR, DEF, and EGR system management. 

Product Features

The 1954664PE Nox Nitrogen Oxide Sensor is manufactured to Cummins factory specifications for monitoring exhaust nitrogen oxide levels.

  • Delivers sensor feedback that allows the ECM to coordinate SCR and DEF system operation.
  • Contributes to accurate exhaust after-treatment management by reporting real-time emissions data.
  • Helps the engine management system detect operating conditions that may generate emissions-related diagnostic codes.
  • Works with multiple emissions control components to maintain proper exhaust system communication.
  • Designed for integration with EPA13 ISX/QSX 15-liter engine emissions systems.
  • Manufactured as a genuine Cummins component for original equipment installation.

Installation Notes

The 1954664PE should be installed in the designated exhaust system location with the sensor connector securely attached and the wiring harness inspected before returning the vehicle to service.
