What is a NOx sensor?
A NOx (nitrogen oxide) sensor is a device that is used to analyse the emissions of a vehicle and determine the amount of nitrogen oxides being produced. It is typically placed before or after the catalyst in the SCR system to calculate if the emissions are at an appropriate level.
