Product Description
SCR / DPF / DEF Emulator – PACCAR MX GHG14 (NOx Sensor-Style Emulator)
🚨 NEW PRODUCT – Emulator designed in the housing of a NOx sensor
This innovative plug-and-play emulator is designed to replace the complete aftertreatment system in trucks equipped with PACCAR MX GHG14 engines.
The device installs directly in place of the downstream NOx sensor, allowing for a quick and simple installation without complex wiring.
Manufactured in Europe using high-quality industrial components, each device undergoes extensive testing and quality control before shipment.
⚠ Important:
After purchase, please provide the vehicle VIN number so the device can be programmed before shipping.

Installation Overview
⚠ Important:
Before installing the emulator, the truck must not be in derate mode.
The EAS ECU must still be electrically functional so the emulator can read the vehicle VIN during initialization.
The upstream NOx sensor must remain operational.
Installation Steps
- Locate the NOx sensor after the catalyst (rear section of the exhaust system).
- Install the emulator in place of the downstream NOx sensor.
- Turn ignition ON – the emulator will learn the vehicle VIN (approx. 1 minute).
- Turn ignition OFF.
- Remove the EAS ECU fuse:
- Peterbilt 579 / Kenworth T680 – Fuse N11
- Peterbilt 389 – Fuse F6
- Disconnect the following sensors:
- PM sensor
- DEF level / quality sensor
- Exhaust temperature sensor
- Turn ignition ON again.
- If all DEF / DPF system errors become inactive, install the emulator permanently in the NOx sensor position behind the catalyst.



Advantages
- Simple installation (NOx sensor replacement)
- Eliminates SCR / DEF / DPF related faults
- Compact and durable industrial design
- VIN-programmed before shipping
