Tata BS6 Phase 2 NOx Sensor – Part No. AAA2128040000

Tata BS6 Phase 2 NOx Sensor – Part Number: AAA2128040000

The Tata BS6 Phase 2 NOx Sensor (Part No. AAA2128040000) is a high-quality emission control sensor designed for Tata commercial vehicles equipped with BS6 Phase 2 diesel engines. It continuously measures the concentration of nitrogen oxides (NOx) in the exhaust gases and sends real-time data to the engine control unit (ECU). This information enables precise AdBlue (DEF) injection through the SCR (Selective Catalytic Reduction) system, helping reduce emissions while maintaining optimum engine performance.

A faulty NOx sensor can lead to increased emissions, reduced fuel efficiency, engine warning lights, derating, or SCR system faults. Replacing a malfunctioning sensor with the correct part ensures reliable operation, compliance with BS6 Phase 2 emission regulations, and smooth vehicle performance.
