The sensor dynamic response should be characterised in order to give a fast and actual esti-mation of the considered. 3 is highly above 5 ppm (critical border: 15 ppm), the sensor has been aged (the chemical element is clogged) and it has to be replaced. All sensors (temperature sensors 25 and 40 and NOx sensors 20 and 45) are connected to an Engine Control Module (ECM), which has the dosing controller running inside.
