Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5WK96754C, 4326867, A045S161, A2C95994000-01, SNS154C
Vehicle Compatibility: Cummins Engines (US Models) – Designed for EPA Tier 4 diesel engines in heavy-duty trucks, buses, and machinery powered by ISB, ISX, and QSB series engines (2014–2023)
Configuration: OEM-style NOx sensor built to deliver precise nitrogen oxide measurements in the exhaust system. Developed for use with SCR (Selective Catalytic Reduction) systems to maintain proper DEF (Diesel Exhaust Fluid) dosing and emission efficiency.
Function: Continuously measures NOx levels in exhaust gases and transmits data to the ECU, optimizing fuel combustion and reducing harmful emissions to meet U.S. EPA compliance standards.
