NOx Sensor Cummins 4327153 | A047R390

Advanced Emissions Monitoring

The Cummins 4327153 Nitrogen Oxide (NOx) Sensor is a critical component designed for heavy-duty diesel engines. It provides real-time data on NOx levels in the exhaust stream, allowing the Engine Control Module (ECM) to adjust fuel injection and aftertreatment strategies. This ensures your vehicle remains compliant with environmental regulations while maintaining peak engine performance.

Key Features and Functionality

• Electrochemical Technology: Utilizes advanced sensors to deliver precise measurements of nitrogen oxide concentrations.
• System Integration: Communicates directly with the ECM to optimize Selective Catalytic Reduction (SCR) efficiency.
• Durable Construction: Built with high-quality materials to withstand the extreme heat and vibration of heavy-duty exhaust systems.
• Emissions Compliance: Helps prevent “derate” conditions by ensuring the aftertreatment system functions within legal parameters.

Engine Compatibility

This sensor is versatile and compatible with a wide range of Cummins medium and heavy-duty engines, including:

• Medium Duty: B6.7, L9, D4.0, F3.8, F4.5
• Heavy Duty & Industrial: X12, QSG12, QSK19, QSK60

Technical Specifications

• Weight: 0.897 lb
• Package Dimensions: 7.25 x 5.0 x 4.0 in
• Position: Typically installed downstream of the SCR system
