Replacing particulate filter differential pressure sensors is an important procedure for monitoring the operation of the exhaust gas treatment system in diesel vehicles. The sensors measure the pressure drop before and after the DPF, allowing the electronic control unit to assess the filter’s clogging level and correctly manage regeneration. Faulty or worn sensors can lead to incorrect filter operation, increased smoke, dashboard errors, and higher fuel consumption.

During service, the sensors are checked, their functionality is evaluated, and they are replaced with new certified components. This allows for the restoration of the exhaust cleaning system’s correct operation and ensures the vehicle’s environmental and operational performance.
