EMRT Professional NOx Sensor Emulator – MAN Euro 4/5
Internal PCB "Stealth" Solution for TGX, TGS, and TGA
 
The EMRT Professional MAN Euro 4/5 NOx Emulator is a high-fidelity PCB-based solution designed for seamless integration into the original hardware. Engineered to be installed directly inside the factory sensor electronics housing, this unit provides a discreet and permanent fix for NOx-related faults while maintaining the original factory appearance and wiring integrity.
 
Key Features
Precise NOx Emulation – Provides a high-accuracy, stable digital signal to the Engine Control Module (ECM), ensuring optimal SCR system operation without triggering fault codes.
Internal PCB Design – Specifically engineered to fit inside the original MAN sensor electronics housing for a clean, "stealth" installation with no wire cutting required.
SCR System Compatibility – Fully compatible with a functioning SCR system. It does not require the system to be disabled, making it an ideal solution for maintaining uptime even when catalyst or AdBlue injector efficiency has declined.
Stable Data Reporting – Delivers consistent nitrogen oxide level readings to the ECM, preventing efficiency-related codes and the resulting torque derates common in heavy-duty MAN applications.
 
Emulated Components
NOx Sensor (Provides stable, high-fidelity nitrogen oxide level readings).
