EMRT Professional NOx Sensor Emulator – Mercedes-Benz Euro 4/5
Hard-Wired Heavy Duty Solution for Actros, Axor, and Atego
 
The EMRT Professional Mercedes-Benz Euro 4/5 NOx Emulator is a ruggedized, wired solution designed for permanent integration into the vehicle's electrical architecture. This module provides a high-fidelity digital replacement for the original NOx sensor, ensuring the Engine Control Module (ECM) receives stable data even when the original sensor has failed or exhaust efficiency has declined.
 
Key Features
Hard-Wired Reliability – Designed for a secure, permanent connection directly into the factory wiring harness or the original sensor connector, providing maximum protection against vibration-induced signal loss.
Precise Digital Emulation – Synthesizes a high-accuracy NOx level signal to ensure optimal SCR system operation and prevent "Check Engine" lights or power limitations.
SCR System Integrity – Fully compatible with a functioning SCR system. It does not require the system to be disabled, allowing your fleet to remain operational while bypassing sensor-specific faults.
Environmental Resilience – When installed according to the provided instructions, the module is fully waterproof and built to survive the extreme temperatures and conditions found in ANZ line-haul and distribution routes.
 
Emulated Components
NOx Sensor (Provides stable, consistent nitrogen oxide level readings via the vehicle's data bus).
 
Compatible Vehicle Models
All Mercedes-Benz heavy-duty models equipped with Euro 4 or Euro 5 engines:
Mercedes-Benz Actros MP II & MP III (The standard for long-distance transport).
Mercedes-Benz Axor (Ideal for regional distribution and construction).
Mercedes-Benz Atego (Reliable medium-duty urban and regional delivery).
 
Installation Overview
This wired module offers the flexibility of a permanent workshop installation:
Identify the NOx sensor wiring on the chassis.
Integrate the EMRT Professional wires into the factory loom (following the color-coded guide).
Seal the connection to ensure a 100% waterproof finish.
Restore full engine torque by clearing any remaining inactive faults with an S-Link HD PRO.
