I have no egr either in the truck as it was all missing when I bought the truck. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. The remaining DPF life is a calculated value based on a number of factors. The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. 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. If you don't notice a voltage change, first test all of their connecting hoses with a pressure gauge. I'm trying to have a vehicle that I can trust at long distances from my home . Free delivery for many products! I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. . You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow. The sensor is located on the Aftertreatment system, mounted directly on the DPF. '6 sMZiMDLWzRu7h55 SDhGCp]%iO '#Tgq&YK_/inyx*TEa"|E$8qRB B8~

You just pull the 2 rubber hoses off. $125.00. Took her out for a spin and to fuel her up (I read somewhere that the DPF will not regenerate if either you've got less than 20 ltrs of fuel or the Oil degredation is below a certain level), by the time I got to the fuel station the DPF Clogging % had dropped to 26.4% so it looks like all is rosey in the garden (fingers crossed).

The parts tend to make up the majority of the cost, usually between $100 and $400, while the labor might only be $50 to $100. While there seems to be benefits to these computer managed engines, they bring a list of problems as well. You dont want to go to all the effort and spend valuable time and money replacing a sensor only to have it fail prematurely because it is a poor-quality replacement part. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). <>
Keep your vehicle turned off while you remove the pressure sensor. At the other point it is used to control the low-pressure exhaust gas recirculation. if so do you have any ideas as to what sensors can be manipulated manually in order to control (activate and deactivate/complete) a regen?

The diesel fuel that normally escapes through the exhaust system during the regeneration cycle only partially burns. The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. I take it you've tried a second static burn?

I just watched an active regen on my 2007 2500. JavaScript is disabled. Category: Exhaust Pressure Sensor / DPF Sensor. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. Since soot is abrasive, when it is mixed with oil, will cause premature wear to the engine components like the bearings. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi. References. If the sensor values on step 5 meet specifications, it is necessary to check the sensor voltage readings further. If the sensor doesnt work properly, it could make your check engine light come on and cause the engine to hesitate or stumble.

\u00a9 2023 wikiHow, Inc. All rights reserved. This diagnostic is typically Diesel Particulate Filter (DPF) Pressure Out of Range High. 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). Let me know if you figured it out and it works, as I'll need to do emissions and if that works I won't have to swap out the exhaust. When diesel particulate matter blocks one or both of these airways to the sensor, the sensor can no longer accurately determine pressure changes, which can result in catastrophic damage to the DPF and ultimately the engine. This also happens when the sensor fails because it leads to the DPF becoming clogged. Also check for pin-to-pin short circuits. If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 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. I'd strongly suggest getting either an "OBDLink" cable or Bluetooth device rather than trying to use an ELM327 device to connect Multiecuscan to your van, MES seems to have no end of issues with the cheap ELM units. It is extremely frustrating when a work truck that is supposed to earn you money is unable to do what it is designed to do because a sensor has failed, and it is even worse when it breaks down and then requires a mobile mechanic and/or a tow to a repair shop to get it fixed and back on the road.
