Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5WK96651A, 05149216AB
Vehicle Compatibility: Cummins Engines (US Models) – Suitable for EPA Tier 3 and Tier 4 diesel engines used in Ram, Freightliner, Peterbilt, and Kenworth vehicles powered by Cummins ISB, ISC, and ISX engines (2012–2022)
Configuration: OEM-style NOx sensor designed for high-precision measurement of nitrogen oxide levels in exhaust gases. Ensures correct operation of SCR (Selective Catalytic Reduction) and DEF (Diesel Exhaust Fluid) systems for emission compliance.
Function: Continuously detects NOx levels in diesel exhaust and sends real-time data to the ECU to optimize fuel combustion and AdBlue/DEF dosing, helping maintain EPA emission standards and improve fuel economy.
