Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). Part NO. A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot. Differential pressure switches that are out of calibration have a tendency exponential the further up the scale you go. Otherwise, you can remove the sensor and test the electrical resistance between the ports. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Last regen was about 900 kms ago. If the soot load is high, a higher pressure difference is observed, because the accumulated soot will provide a restriction to flow on the DPF inlet side (Inlet pressure > Outlet pressure). So if the front hose reads 1 PSI and the rear hose reads half PSI, the signal wire voltage should read somewhere around .8 volts. Finally, if youre looking to save money over OEM prices, consider an aftermarket DPF pressure sensor from a company based in North America.
