Exhaust Gas Temperature Sensor For MERCEDES MP2 MP3 A0061530828 MP0061530828 Application The exhaust-gas temperature sensor A0061530828 (also catalogued as MP0061530828) is screwed into the exhaust pipe just upstream of the diesel particulate filter on Mercedes-Benz Actros MP2 and MP3 trucks (model years 2002-2013) as well as Axor and Axor-2 chassis. It continuously measures pre-DPF gas temperature and feeds the data to the ECU so that active regeneration is triggered when the reading exceeds ~580 °C; a correct signal prevents torque de-rates, DPF blockage and dashboard MIL illumination.
