Why Replacement is Important:

A functioning NOx sensor is vital for accurate measurement of nitrogen oxides in the exhaust system. If the sensor fails or reports incorrect data, the ECU may mismanage urea dosing in the SCR system, leading to higher emissions, fault codes, reduced engine efficiency, and potential damage to aftertreatment components. Timely replacement ensures proper NOx regulation, maintains engine performance, prevents emission violations, and prolongs the life of SCR and DPF systems. Regular maintenance of the sensor safeguards compliance with environmental regulations and ensures optimal operation of diesel engines.
