You will never receive any spam from me. wikiHow is where trusted research and expert knowledge come together. Keep your vehicle turned off while you remove the pressure sensor. Subscribers do not see these advertisements, To join in you must be a member of MotorhomeFun. 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). Has this been figured out, I'm almost due for a test and not interested in finding and swapping out the exhaust. It may not display this or other websites correctly. The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. Consult the wiring diagram and check the wires. 888.99.DIESEL. DPF-R will do the trick used one for about 8000 miles with no problem. Product Introduction. Turn on the ignition switch without starting the engine. At the other point it is used to control the low-pressure exhaust gas recirculation. $104.63 + $12.00 shipping . Thank you in advance for your support! You can buy replacement sensors from auto parts stores and they usually cost around $100150 USD.

The ECM activates the STOP ENGINE lamp immediately after a DPF differential pressure fault is determined to be active. TruckPartsAlley(dot)Com at Bonanza - Parts & Accessories, Car To find a high-quality new DPF replacement pressure sensor, its important to purchase the right part. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. ya EGR has A LOT of sensors/modules tied into it. i pretty much gave up on figuring out a way to simulate EGR readings which is why i left mine in tact just plug it all in for testing. +5 Volt supply, ECM Return, DPF outlet pressure signal, DPF differential pressure signal. 7.If needed, shorten the tubes to achieve a 0-10 degree sensor tube down angle. Fault codes 1881 and 3134 should become active. JavaScript is disabled. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. Vacuum pumps measure how much pressure builds up inside the sensor when you add more air. If all's well on this end then it should show 12 volts or more when reading from the devices scale! You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow. I played with my truck and found I can run the CMC tier3 ECM on my truck and everything runs like a champ, its only a 260hp tune at 3000rpm high idle but it worked working on how to bump max speed on that ECM with EFI Live as we speak. If the soot load on the DPF is high, the ECM will activate the DPF system warning lamp on the dashboard. Previous Post Normal DPF Differential Pressure - DPF Alternatives NWA It is not easy to miss there are two flexible pipes connected on the sensor body. Replace the whole assembly). You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. Monitor DOC inlet pressure sensor voltage pin 87. I love learning about how everything works and then explaining complex systems in a way that everybody understands. This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.
