The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF. Sometimes the DPF is misdiagnosed as the problem and replaced only to quickly fail again because the sensor is the actual issue. If you still cant find the pressure sensor in your vehicle, take your vehicle to a mechanic since the sensor may be built into the pipes.
