NOx Sensor Repair

What is a NOx Sensor?

Since the early 2000s, diesel vehicles have had NOx sensors fitted, and now modern petrol vehicles often also have them. They are important for managing emissions, which is important not only for environmental reasons but also for air quality and people’s health.

A NOx sensor works by monitoring the levels of Nitric Oxide your vehicle is releasing into the air and controlling the emissions with a Selective Catalytic Reduction (SCR) system. Your petrol or diesel vehicle must have a NOx sensor to pass Euro 6 compliance tests.
