The NOx sensor detects nitrogen oxides via an electro-catalytic mechanism. This is done via a working electrode which features a material that reacts with NOx. A voltage is then passed through an electrolyte, and this determines how much NOx is present in the vehicle’s system.

Why are NOx sensors expensive?
Another drawback of amperometric NOx sensors is their high cost due to the multiple chamber design and the requirement for complex electronics to detect nanoampere current levels.
Can a NOx sensor be repaired?
The NOx sensor is a very complicated component and can be expensive to repair however, it's often not actually the sensor that is causing the problem but the lambda probe inside the exhaust which tests the NOx levels which have malfunctioned, and this is something that can easily be replaced.
How do you reset a NOx sensor?
Go to the System menu, select Engine, then choose the specifics for your vehicle and go to Functional Tests, followed by Special Functions. At the next screen pick Adaptations then scroll down to find Reset Learned Values Of NOx Sensor Upstream And Downstream Of SCR Catalytic Converter.Sep 10, 2020

What is a NOX sensor?
A NOx sensor is a part of an SCR system that measures the amount of nitrogen oxide in a vehicle’s exhaust. This way, the SCR knows the proper amount of urea or ammonia in order to provide better fuel economy and less harmful emissions. A Jesben branded NOx sensor.
How does a NOx sensor work?
A high-end NOx sensor works by employing an electrode which in turn contains a small amount of material that reacts with nitrogen oxides. This is called a catalyst and is often made out of titanium oxide, activated carbon, and other base metals.
How does a NOX sensor work?
This is done via a working electrode which features a material that reacts with NOx. A voltage is then passed through an electrolyte, and this determines how much NOx is present in the vehicle’s system.
How to fix a faulty NOx sensor?
Firstly, you’ll need to run a diagnostic on your vehicle. If the codes point to the NOx sensor being at fault, you should contact Xenons4U for advice and to order any spare parts you may need to repair it. If the probe is the issue, you should then follow this step-by-step guide:
What happens if you have too much NOx?
If too much NOx is detected, the sensor will feed this information to the SCR system, which can then adjust its output accordingly so that the vehicle continues to meet emissions regulations. If you own a diesel-powered car, the NOx sensor is critical to the SCR system to ensure your vehicle is compliant.
What is the source of reduction in diesel exhaust?
The source of reduction is typically automotive-grade urea, which is also known as Diesel Exhaust Fluid. When this fluid is released, it creates a chemical reaction which converts nitrogen oxide into harmless nitrogen, water, and carbon dioxide, before it is expelled via the exhaust tailpipe of a vehicle. If you drive a newer diesel vehicle, it’s ...
