Description
Product Overview
Part Name: Nitrogen Oxide Sensor (NOx) – Upstream
Part Numbers: A0101531428
Vehicle Compatibility: Mercedes-Benz Trucks – Designed for Actros, Arocs, and Axor Euro V–VI models (2013–2024). Installed upstream (before the SCR catalyst) to monitor raw engine-out NOx emissions for real-time ECU adjustments.
Configuration: OEM-style NOx sensor equipped with stainless-steel probe, durable ceramic sensing element, and integrated electronic control module. Built to handle extreme exhaust temperatures and provide high-accuracy measurements.
Function: Detects NOx levels in untreated exhaust gas and sends data to the engine ECU. Enables precise air-fuel ratio adjustments, improves combustion efficiency, and ensures emission compliance by optimizing the SCR process.
