Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5WK97102_, A2C93842800-01
Vehicle Compatibility: Cummins Diesel Engines (US Models) – Designed for EPA Tier 4 emission-compliant Cummins ISX, ISB, and QSX diesel engine platforms used in trucks, buses, and off-highway vehicles (2014–2024)
Configuration: OEM-style NOx sensor manufactured for precise measurement of nitrogen oxide levels in diesel exhaust gases. Built for high resistance to heat and vibration, ensuring consistent and accurate performance in all driving conditions.
Function: Monitors NOx levels in exhaust gases and sends real-time data to the ECU to control DEF (Diesel Exhaust Fluid) injection. This helps maintain emission compliance, improve combustion efficiency, and reduce fuel consumption.
Technical Specifications
