Replacing the NOx sensor
- Around 500-1200 EUR will get you a new NOx sensor to replace the faulty one on your vehicle. While it is an ideal solution, you still run a risk of it happening in the future, meaning that there will be more money spent on repairs.
-
Purchasing a refurbished NOx sensor
- Refurbished NOx sensors are very commonly found in garages, services and part shops. They are cheaper than new NOx sensors (around 1.5 times cheaper) and can serve just as well as a new one, though these typically do not have warranty included and they might not serve as long as new sensors. In the end they do not solve the main issue of reliability as well.

Installing a NOx emulator
- NOx emulators are electronical devices which imitate a fully working NOx sensor. Usage and installation is quite simple – connect a few wires to the vehicle and you will have full imitation of the NOx sensor within your vehicle. Best thing? They are many times cheaper than NOx sensors and they can also be used with a faulty catalyst saving you a large amount of money otherwise spent on repairs.
- Hooking up a heavy duty diagnostic system Carfans C800 heavy duty scanner can diagnose and reset NOX sensor on multi-brand trucks. Fcar F3-G, Autel and Launch GDS universal scanners do not work on NOx sensor. There are also single brand service tool that will reset NOx sensor on specific trucks, i.e Insite for Cummins engine, SDP3 (Scania Diagnose & Programmer 3) for Scania heavy duty.
