Always work outdoors or in a well-ventilated space when running your vehicle to prevent harmful fumes from building up. You just pull the 2 rubber hoses off. Check the condition of the air filter. I would think if it was not burnt and had good contacts it should be just fine but instead so many guys just change it out ! At one point it reports the charge status of the particle filter and monitors its function. For this investigation, an SKC pocket pump with integral pressure transducer (SKC Inc., Eighty-Four, PA) was used to collect the . However, replacing the DPFE sensor is a simple task that can be done with a few everyday tools. 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.

The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. $159.59. . Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. You can buy vacuum pumps online or from auto part stores. The DPF differential pressure sensor (DPS) has two pressure sample lines. , 2501 boost pressure regulator signals fault 2626 DPF soot content too high for regen. You must log in or register to reply here. $145.00 + $9.45 shipping. That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. 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). The voltage should read a value between the pressure values of both hoses. You'll need a multimeter set to 20V and a pressure gauge to test it. The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. If all's well on this end then it should show 12 volts or more when reading from the devices scale! I take it you've tried a second static burn? If you notice the rubber hose has cracks or damage, replace it as soon as you can since it may leak later on. Using DDDL go to service routines> SCR & DPF voltages. The correct oil is hard to find and spendy . Ash is stored in the DPF. The Fora platform includes forum software by XenForo. for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? The test runs for 30 to 60 minutes approximately. One of the major complications these suffer from is the DPF - the Diesel Particulate Filter. These cookies ensure basic functionalities and security features of the website, anonymously. Connect your preferred diagnostic tool, read and list all other active fault codes OR inactive fault codes with more than one counts in the last 25 operating hours. Spare Mini in my closet. Also Mike, I do not idle it very long at all . Keep your vehicle turned off while you remove the pressure sensor. Remove Bimmerpost Model Selection. The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. Variation: If you have trouble keeping the probes against the pins, opt to use ones that have alligator clips and attach them to the pins so you dont have to hold them in place. DPF ash loading: Burned soot leaves ash behind. If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. Vacuum pumps measure how much pressure builds up inside the sensor when you add more air. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. This filter traps particulate matter (also called "soot") created by the engine. Connect your diagnostic tool and monitor the fault code page. 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! Useful articles and Training courses about Diesel engines. To replace it, simply remove the old one and replace it with the new one.

If they are found to be damaged or plugged, replace or repair as necessary. The engine should start with the signal wire back-probed. x[G?Gr2FMOf$yD$Vd"k44vd/~o>{{O_/_|~xO}^w/U|?&yGY}\X7unrz3sTo&u|Ss5oqsCTmt^Z1%&M)foo7y'CenBQnZcu,f3Ouj`n814m7sya\9=b9sH3VD.

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 . Brand: LAPB 4 ratings $13000 FREE Returns About this item Original DFN Pressure sensor for Cummins We offer 12 Month warranty on this part. 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.

Will be replacing the Y-cable tomorrow, then re-testing. Typically, the sensor is held in place with a Torx bolt and screws. Check if the signal of the aftertreatment temperature sensors is within specifications. Opt for a digital multimeter since they can perform multiple functions and will be easier to read while testing the sensor. I love learning about how everything works and then explaining complex systems in a way that everybody understands.
