The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. $159.59. . Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. You can buy vacuum pumps online or from auto part stores. The DPF differential pressure sensor (DPS) has two pressure sample lines. , 2501 boost pressure regulator signals fault 2626 DPF soot content too high for regen. You must log in or register to reply here. $145.00 + $9.45 shipping. That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. 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). The voltage should read a value between the pressure values of both hoses. You'll need a multimeter set to 20V and a pressure gauge to test it. The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. If all's well on this end then it should show 12 volts or more when reading from the devices scale! I take it you've tried a second static burn?
