Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed. underneath/Bed extender/50-gal diesel tank/ 12K Winch/Nerf bars/ Etc. The exact location of the DPS varies by vehicle model type such as medium duty, pickup, or van.

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. $104.63 + $12.00 shipping . Also check for pin-to-pin short circuits. Turbocharger faults: 1898, 2198, 2387, 2449, 2634, 2635, 2636, 3616 https://bit.ly/3HFLFDuWant to work with our channel? P r e p a r a t o r y S t e p s WA R N I N G Batteries can emit explosive gases. If you bring your filter into a DPFCleaning.com center, we'll check the filter over and give you a condition report as to whether the filter can be cleaned or not. Fired her up and instantly got totally different readings with no error codes. New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube. The ECM activates the STOP ENGINE lamp immediately after a DPF differential pressure fault is determined to be active. They worked, but I had the CEL. At ambient temperature25C (77F) and below: Voltage reading should be between 0.61 and 0.77 Volts. It's important to rev the engine and check for voltage changes before testing anything else. General DPF faults: 2754, 3133, 3134, 3135, 3316, 3317, 3318, 3319, 3321, 3322, 3396, 5383 . Industrial differential sensors may be integrated into a standardised fitting, allowing it to be built into existing pipework. The sensor monitors and measures the pressure with the EGR valve. The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. Differential pressure sensors are typically packaged with two ports to which pipes can be attached. Going to get it on a mates pit at weekend and double check for blockages in the sensor pipes more thoroughly, mine sits at max 14mbar whilst idling which still seems high, possibly. Damaged DPF. Use channel exclusive promo code road3333 to get 12% off of your order today. Check my guide on how to create an account, training courses on how to use QuickServe Online effectively, you can even rent one from Diesel Laptops. But.even if you know the pressure how do you propose measuring it. The ECM constantly monitors the soot load of the DPF. If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 Follow along with this simple testing method. Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 You are using an out of date browser. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. what im trying to do is to actualy fool the ecm into thinking it is performing a regen successfully when it goes into a timed (forced) regen. The DPF differential pressure sensor is a different sensor that is necessary for filtration to function effectively. However, replacing the DPFE sensor is a simple task that can be done with a few everyday tools. You must go through each step until the end to eliminate the possibility that more than one fault codes trigger 1922. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi. GiU#5.R ^1Vq7W~w:5|g*?,LUUsiB,}c" 6#va\lg? 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. Will be replacing the Y-cable tomorrow, then re-testing. Although a three tenths of a PSI doesn't sound like much, I still wonder if there . Perform the Aftertreatment Diesel Particulate Filter Regeneration Analyzer Test (ensure that you have at least 250 MB space on your hard drive). Up to 9.5 mm [3/8in] can be cut off the aftertreatment DPF differential pressure sensor elbow fitting end of each DPF differential pressure sensor tube. 2011,4wd LB/CC 2500 H&S Mini MCC by Tomeygun, BD protect 68rfe VB seperator plate enhanced stall triple disk TC, Super B 64.5/80/.91 3rd gen mani & inline EB, Arp 425s, Fass Titanium 95. I have that same scanner, it has allot of good info like that but if you don't know what parameters are good and or poor it's kind of useless. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The engine may get hot while youre working so avoid touching it so you dont get burnt. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. $125.00. Consult OEM factory service information for the exact vehicle specs if needed. Bimmerpost Model Selection. This step will only work if you use Cummins Insite (version 8.5.2 or later) or an equivalent diagnostic tool which supports the test described below. for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ?
