Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5593951, A062U284
Vehicle Compatibility: Cummins Diesel Engines (US Models) – Designed for EPA Tier 4 emission-compliant ISX, ISB, and QSX engines commonly found in heavy-duty trucks, buses, and off-road machinery (2014–2024)
Configuration: OEM-style NOx sensor constructed for high-accuracy exhaust analysis. Engineered with durable materials to resist extreme heat, corrosion, and vibration, ensuring reliable data transmission to the ECU under heavy-duty conditions.
Function: Monitors nitrogen oxide concentration in exhaust gases and relays this information to the ECU. Enables efficient DEF (Diesel Exhaust Fluid) injection control for reduced emissions, optimal combustion, and regulatory compliance.
Technical Specifications
Type: Nitrogen Oxide (NOx) Oxygen Sensor
