NOx Sensor Cummins 4326870 | A045S167, 2872944

Product Overview

The Cummins 4326870 NOx Sensor is a critical component of the heavy-duty exhaust aftertreatment system. This sensor is specifically engineered to monitor the levels of nitrogen oxide in the exhaust stream, providing real-time data to the engine control module to ensure compliance with environmental regulations and maintain peak engine efficiency.

Key Features

• Precise Monitoring: Accurately measures NOx concentrations to optimize the Selective Catalytic Reduction (SCR) system.
• Enhanced Durability: Built to withstand the high temperatures and harsh conditions of heavy-duty diesel exhaust environments.
• Fuel Efficiency: Helps maintain the correct air-to-fuel ratio, contributing to better fuel economy and reduced operational costs.
• Direct Replacement: Designed for seamless integration with Cummins engines using part numbers 4326870, A045S167, or 2872944.

Technical Specifications

This nitrogen oxide sensor is essential for modern diesel engines to function within legal emission limits. Failure of this sensor can lead to “limp mode” or reduced engine power, making timely replacement vital for fleet uptime.
