Short the +5V SUPPLY pin to the Differential Pressure SIGNAL pin (NOT the outlet pressure signal pin! TROUBLESHOOTING: Check for other fault codes, if codes 3609/3 or 3609/4 are present. Come join the discussion about reviews, drivetrain swaps, turbos, modifications, classifieds, builds, troubleshooting, maintenance, and more! At the other point it is used to control the low-pressure exhaust gas recirculation. 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. <>/Font<>/Pattern<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> The online store you use should provide you with access to industry experts to help you if you run into an unexpected problem changing the sensor.

I'm trying to have a vehicle that I can trust at long distances from my home . Last regen was about 900 kms ago. My understanding is that the 40420 does not have DPF delete capabilities. I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..? wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. for example on a deleted truck that the aftertreatment system hasnt been disabled only codes shut off, the truck will want to go into a timed/forced regen even though there is no DPF. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). When the diesel particulate filter is not regenerating properly due to the faulty DPF sensor failing you may experience some of or all of the below symptoms: A DPF pressure sensor is necessary to keep the DPF free from diesel particulate matter and soot, and if the DPF is plugged, the regeneration process will not fix it. Product Detail. If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. Another ? This HAS to make a diff in how it runs though..theres no way it can run right without an accurate reading, can it? NEW Genuine Cummins OEM differential pressure sensor 4384138. Enter your email address to receive access to exclusive offers. F40Model Year: 2019 + . for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? The DPF differential pressure sensor can stop signaling to the PCM for regeneration. if not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. Cummins DPF Differential Pressure Sensor - 2871960. Clean or replace as necessary. Will be replacing the Y-cable tomorrow, then re-testing. P2454 GMC Diesel Particulate Filter Differential Pressure Sensor Circuit Low Voltage. One of the major complications these suffer from is the DPF - the Diesel Particulate Filter. An air leak would change the sensor readings, thus resulting in the code. Product Introduction. I love learning about how everything works and then explaining complex systems in a way that everybody understands. In other words the higher the differential the faster it goes up the scale. 2022/3500/6.7/68RFE/Crew C/SB/SRW/TRXOFFROAD Decals/Tradesman/4X4/FRTRPLBPR/TOOLBOX/RCHTRK/ 275 MTR's KEVLAR/ 2" leveling kit Front/1" rear/Metal Grid Protec. Not if you can take control of the regen fuel map, it's there just have to find it, I can adjust it on engineering level insite on off road engines, can adjust the fueling value and the timing from almost less than a trickle to 2000* EGT temps.. now you're thinking! wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational. P2454 Ford Diesel Particulate Filter Pressure Sensor 'A' Circuit Low. It's going to want to close turbo down and open EGR valve until it see pressure Take the butterfly out of the throttle and leave EGR in place but blocked off with plates Then setup another resistant mosfet to simulate a pressure in the EGR to keep that readiness monitor happy.

The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. EGR differential pressure faults: 1866, 2273, 2274. Also again ,, I know that I am running the wrong oil [ 229.5 instead of the 229.51] but I'm planning on a GDE delete of EGR and DPF so I'm thinking it will be OK to run this oil after the delete . Naturally, a small pressure drop is always expected even on new DPFs, due to the fact that the exhaust gases are foreced to flow through the DPF walls.

I had a conditional pass but only aloud that one time, now need to fool it or return to stock. Your multimeter may also be labeled with the letter V with 3 horizontal lines on top of it instead of DCV. It does not store any personal data. Proceed to check the condition of the ports on the EGR mass mesurement flow assembly. The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing.

I take it you've tried a second static burn? CUMMINS DPF Differential Pressure Sensor 287196. The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. Diesel Oxidation Catalyst (DOC) faults: 3313, 3314, 3315, Faults that could be causing excessive soot generation, Fuel System faults: 559, 1139, 1141, 1142, 1143, 1144, 1145, ,4713 You are using an out of date browser. Where should you buy your replacement DPF sensor should it need to be replaced? Can anyone advise on what the typical DPF Sensor readings in mbar would be in the following situations..? Check if the signal of the aftertreatment temperature sensors is within specifications. The code DOES NOT mean that the DPF needs to be replaced immediately. I'd like to get the GDE tune and am also considering deleting the DPF because I want a reliable van that doesn't leave me stranded hours from home on a regular basis. Ended up finding a lot more information I wanted to learn. The sensor hoses can become clogged from soot in the exhaust system just like the DPF. Baking that style of filter isn't always a sure thing because of the way it's build. The voltage should read a value between the pressure values of both hoses. While there seems to be benefits to these computer managed engines, they bring a list of problems as well. Typically, the ground port is the leftmost or rightmost prong but it may vary depending on the sensor you have. Ram Cummins with lots-o-mods.

The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. <>>> A Diesel particulate filter helps to trap dust and other debris that might otherwise cause the pressure to rise in your diesel engine. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. Depending on the measured soot load, engine torque output will be reduced. Drawback of Mean Value Pressure Drop Approach - Particulate Micro- . . Sent from my H1611 using Tapatalk. The DPF system is still used on commercial trucks today.
