My specialization is diesel engines and electronic management systems. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash. One sensor that keeps an Eagle Eye on the condition of the DPF is the Differential Pressure Sensor.How can we test this sensor and how can we be sure that the ECU is processing what it sees? The pressure sensor location is a bit different for each make and model. I have seen other report as low as 3mbar. Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it .

I suppose we could compare notes and perhaps get a baseline from newer vehicles but probably the best thing to do (if the vehicle is otherwise running normally) would to be to just look for any significant negative changes or trends over time. Ram Cummins with lots-o-mods. Excessive ash in the DPF, causes blockages. Free shipping. JavaScript is disabled. In this manner, the sensor is able to determine the pressure difference across the DPF, which serves as the primary input data the PCM uses to determine the soot load, and therefore, the efficiency of the DPF.
