Euro 5 Volvo Euro 5 NOx Sensor Emulator | SCR Delete Fix
A plug-in NOx sensor emulator for Volvo Euro 5 trucks that permanently resolves NOx sensor faults and torque derate — no wiring modifications required.
Volvo Euro 5 trucks are dependable workhorses on heavy-haul and long-distance routes, yet the SCR/AdBlue system's NOx sensor is vulnerable to failure under demanding operating conditions — leading to power derate and persistent warning lamps that stop fleets in their tracks. Operators seeking a Volvo Euro 5 NOx sensor delete or SCR emulator will find that this device produces upstream and downstream signal values precisely matched to the Euro 5 ECU architecture, keeping the engine management system in faultless operation. Once installed, the truck continues running without limp mode or fault code interruptions.
How Does It Work?
The emulator connects directly to the vehicle's original NOx sensor electrical connector — no wire cutting, no soldering. It continuously supplies the Volvo Euro 5 ECU with the upstream and downstream NOx signal values it expects, replicating the behaviour of a fully functional sensor. With the engine management unit receiving a normal signal profile, it does not generate fault codes and does not trigger a power restriction.

Will the Volvo Euro 5 NOx emulator work on Volvo Euro 6 trucks?
No. This product is designed specifically for Volvo trucks on the Euro 5 emissions standard. A dedicated product is available for Euro 6 vehicles.
Will existing fault codes clear automatically once the emulator is fitted?
