Cars with modern diesel engines are equipped with additional exhaust gas processing systems to reduce the harmful emissions, which helps meet the increasingly strict emission regulations. Special additions help the catalyst decompose nitrogen oxide into water and nitrogen. In order for the system to work properly, the pumping module must be equipped with a pressure sensor. If it fails, the harmful nitrogen compounds are no longer decomposed and the sensor needs replacing.
