NOx stands for the most important nitrogen oxides, namely nitrogen monoxide (NO) and nitrogen dioxide (NO2), and consists of the atoms N (nitrogen) and O (oxygen).
NOx sensors measure the concentration of oxygen and nitrogen oxide in the composition of the exhaust gas and can be located behind and in front of the SCR catalyst.
They make it possible to check the functionality of the exhaust gas cleaning system and determine exactly when maintenance should be performed or when defective components need to be replaced.
The NOx sensors from Diesel Technic are suitable for a number of Scania models.
DT recommends before replacing the sensor, to check the sensor wiring for damage and contact resistance; also check the exhaust system for damage and leakage.
