High Class Service Truck. DPF Differential Pressure Sensor - Consensus. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. In other words the higher the differential the faster it goes up the scale. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Soot load is estimated by the ECM, by monitoring the inlet and outlet pressure of the filter. Since soot is abrasive, when it is mixed with oil, will cause premature wear to the engine components like the bearings. Please use the following link when ever using Amazon.com. if it was fully clogged), then proceed to step 9. Learn more An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicles exhaust before and after it passes through a filter. x]ioFW;2yK++uA0]F+jd)A-3Y&69mG2:)J;eUSvm~rL|k\YLu=_&D0OEbDHr4tZNNGyy7v~:{;{\Sul+izT8=1O({ 4y~:uM^-IW{ju1s>OIL>~|~"~*nn,j>RbFi^mmdRXFO*9`

The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. However, replacing the DPFE sensor is a simple task that can be done with a few everyday tools. 1. This image may not be used by other entities without the express written consent of wikiHow, Inc.

Assuming that you validated your repair after each step that youpreviously followed (run engine, test drive etc): If fault code 1922 is still active OR inactive with more than one counts in the last 25 operating hours, the DPF is fully clogged. Once you are done, connect all components, validate your repair and proceed to the next steps below. Check for EGR differential pressure sensor blockage. Follow along with this simple testing method. ARghh.. Not again.. Product Introduction. The symptoms of a diesel particulate filter differential pressure sensor malfunction are not always easily detected because they mimic many of the symptoms of other components of the diesel emissions systems failing. 4.6 V depending on differential pressure.

The vehicle then ran fine for about 197km then the background regens kicked in (no light on dash) and these were occurring every 1-16km according to Multiecuscan, which is when I get white smoke bellowing . This filter traps particulate matter (also called "soot") created by the engine. DPF SENSOR !!!!!!!! We know the equipment AND service end of the emissions industry! Avoid using your vehicle if you dont have the sensor attached since it will cause unfiltered exhaust fumes to escape.

If we can find it, we should be able to cut post inject to next to nothing where as when the regen is initiated there is actually nothing happening externally but you are telling the ECM that is is happening and it's happy. Simply the best offers on diagnostic tools for the US market. If the soot load on the DPF is high, the ECM will activate the DPF system warning lamp on the dashboard. Fault codes 1879 and 3134 should become active. I have seen other report as low as 3mbar.

Useful articles and Training courses about Diesel engines. How does a DPF pressure sensor work? Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed. DPF differential pressure sensor tubes to achieve a 010 degree sensor tube downward angle. Level up your tech skills and stay ahead of the curve. The Pressure Differential Sensor on your 6.7L Cummins tells the ECM how "full" your DPF is. Engine misfire: 1654, 1655, 1656, 1657, 1658, 1659 You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. To replace it, simply remove the old one and replace it with the new one. Your multimeter may also be labeled with the letter V with 3 horizontal lines on top of it instead of DCV. These are signs that the DPF sensor is dying, and the DPF may not correctly regenerate. Exhaust gas pressure - 120-150" Hg - Low could indicate a failing turbo.
