Description
Product Overview
Part Name: Nitrogen Oxide (NOx) Sensor – Downstream
Part Numbers: 51154080031
Vehicle Compatibility: MAN Trucks – Compatible with TGX, TGS, and TGM Euro V–VI heavy-duty trucks (2013–2024). Installed downstream of the SCR catalyst to monitor treated exhaust gases and maintain emissions accuracy.
Configuration: OEM-standard downstream NOx sensor featuring a stainless-steel probe, high-temperature ceramic element, and integrated electronic controller. Designed to endure harsh exhaust conditions and provide precise feedback to the ECU.
Function: Measures NOx levels after catalytic treatment to confirm the SCR system’s performance. Transmits real-time data to the ECU to adjust AdBlue dosing and ensure optimal emission reduction and fuel efficiency.
