GPD 1815145 Nitrogen Oxide NOx Sensor for Cummins Diesel Engines

The GPD 1815145 is a direct-fit nitrogen oxide (NOx) sensor designed for heavy-duty diesel engine applications equipped with SCR (Selective Catalytic Reduction) aftertreatment systems. This sensor provides accurate real-time measurement of nitrogen oxide emissions to ensure optimal engine performance, emissions compliance, and fuel efficiency.

Key Features:

• Direct replacement for Cummins OEM part numbers 2872948, 4326873, 4326873-RX
• Compatible with multiple heavy-duty applications including Autocar, Blue Bird, Mack, and Peterbilt vehicles
• 42.44-inch overall length with 915mm (36-inch) wire harness
• 4-pin rectangular connector with black housing and female connector gender
• Male blade-type terminals for reliable electrical connection
• 12-volt operation for standard diesel engine electrical systems
• Designed for tailpipe/outlet position monitoring

This NOx sensor monitors nitrogen oxide concentration in exhaust gases and transmits data to the engine control unit (ECU), allowing the system to adjust engine parameters for reduced emissions and compliance with environmental regulations. Essential for maintaining proper SCR system operation and avoiding diagnostic trouble codes.
