The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape. . If the DPF has already been replaced during the repair (eg. At ambient temperature25C (77F) and below: Voltage reading should be between 0.61 and 0.77 Volts. It is also possible to check your DPF differential-pressure reading with a multimeter. Cummins Quickserve Online Account for FREE! 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. Some product links are affiliate links which means if you buy something we'll receive a small commission. Exhaust gas pressure - 120-150" Hg - Low could indicate a failing turbo.

The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing. Once the test is completed, record the results and follow the instructions on the diagnostic tool. If the sensor values on step 5 meet specifications, it is necessary to check the sensor voltage readings further. The differential pressure sensor is one of the sensors in the diesel emissions system that communicates with ECU and the power-train control module (PCM) critical information about exhaust backpressure caused by the accumulation of diesel particulate matter (DPM) or soot. He has more than three years of experience writing for and working with wikiHow. +5 Volt supply, ECM Return, DPF outlet pressure signal, DPF differential pressure signal.
