The pressure sensor location is a bit different for each make and model. Components not supplied by Cummins are not covered under this Plan. Warehouses - Fleet or Partner Pricing Available. The exhaust backpressure will build and with nowhere to go can end up back in the combustion chamber causing the soot to mix with the engine oil. A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF. You are using an out of date browser. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. The exact location of the DPS varies by vehicle model type such as medium duty, pickup, or van.

We are also having troubles with dpf sensor. The engine may get hot while youre working so avoid touching it so you dont get burnt. 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. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. % This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. By comparing the pressure at these two points, the sensor can track the buildup of soot within the DPF and trigger the PCM to do a regeneration cycle at the appropriate time. This article was co-authored by wikiHow staff writer, Hunter Rising. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. if i can manipulate the DPF sensor to try and control and fool the ecm into thinking the regen cycle is working and complete it i can then have a deleted truck that will pass obd2 emissions. You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow.

Typically, the sensor is held in place with a Torx bolt and screws. Diesel emissions systems rely on sensors to send signals to control modules when maintenance on the aftertreatment systems is required or when something is no longer functioning properly and requires a repair. This also happens when the sensor fails because it leads to the DPF becoming clogged. The code DOES NOT mean that the DPF needs to be replaced immediately. To find a high-quality new DPF replacement pressure sensor, its important to purchase the right part. 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` yL"g6S`V5K*JMIAhVrYgj'zQeJATelu*lj=E5,dYtN>*QNw]gkozj!ENDa!23mc2yN>iRb4teQFEeTrtf>a,HuXxXTO)9O.=x&:Mk6>TRA5i9N/Z!*$Y(S wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. The remaining DPF life is a calculated value based on a number of factors. You can buy vacuum pumps online or from auto part stores. Keep your vehicle turned off while you remove the pressure sensor. You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. If you notice the numbers changing on the multimeter display, then the sensor has electrical resistance, meaning a current can pass through it and it will still work in your vehicle.
