Cummins Dpf Differential Pressure Sensor Reading If you are working in a diesel engine, then you know how important it is for the engine to have a good diesel particulate filter. While there seems to be benefits to these computer managed engines, they bring a list of problems as well. Last regen was about 900 kms ago. Also Mike, I do not idle it very long at all . To find a high-quality new DPF replacement pressure sensor, its important to purchase the right part. Depending on the measured soot load, engine torque output will be reduced. 23.65. Check the condition of the air filter. Following verification, proceed to the next steps. Here is the link to the PDI tuner I have installed on my truck: https://www.amazon.com/dp/B087V9XWB7/?tag=ryannsophia-20Welcome to our channel! whether or not its possible id definitely appreciate any help as i dont know about resistors and would definitely like to try this out was thinking of wiring up something to a set of switches that when flipped it will progressively fool the sensor into thinking the filter is actively cleaning or becoming blocked. Level up your tech skills and stay ahead of the curve. Method . If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. Check if the signal of the aftertreatment temperature sensors is within specifications. To reduce the possibility of personal injury, always ventilate the compartment before servicing the . Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. 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. The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. Product Benefits: Quality Control Cost Effectiveness High System Accuracy . Guys, my MD802 is telling me that the DPF is too clogged to regen so I'm assuming that it can only be cleaned by taking it out and manualy cleaning it , chemical or roding it out ??

DPF differential pressure sensor signal voltage. You'll need a multimeter set to 20V and a pressure gauge to test it. 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. Today's and tonight's Amsterdam, North Holland, Netherlands weather forecast, weather conditions and Doppler radar from The Weather Channel and Weather.com % When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. It is not easy to miss there are two flexible pipes connected on the sensor body. Sent from my H1611 using Tapatalk. National Truck Parts has a large selection DPF and emissions products for heavy duty trucks. Otherwise, you can remove the sensor and test the electrical resistance between the ports. Thanks to all authors for creating a page that has been read 45,868 times. Learn more An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicles exhaust before and after it passes through a filter. Subscribers do not see these advertisements, To join in you must be a member of MotorhomeFun. Baking that style of filter isn't always a sure thing because of the way it's build. Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational. If all's well on this end then it should show 12 volts or more when reading from the devices scale! Cummins provides sensors that support a multitude of critical components on your engine - from controlling the speed of the turbocharger to assisting the level of NOx taken into the aftertreatment system. These diagnostic trouble code refer to the condition of the exhaust gas GiU#5.R ^1Vq7W~w:5|g*?,LUUsiB,}c" 6#va\lg? Your multimeter may also be labeled with the letter V with 3 horizontal lines on top of it instead of DCV. The DPF differential pressure sensor is located on the back of your car's engine compartment. idling) might require a stationary regeneration, due to the fact that the average temperatures on the DPF are not enough to allow soot to be burned off passively. This also happens when the sensor fails because it leads to the DPF becoming clogged. References. If the aftertreatment DPF differential pressure sensor voltage readings are within specification, then proceed to the Linked Solutions section. TROUBLESHOOTING: Check for other fault codes, if codes 3609/3 or 3609/4 are present. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. If not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). The sensor monitors and measures the pressure with the EGR valve. This keeps this site running and allows me to keep creating content. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output. You can buy metal T-pins from hardware stores or online. Enter your email address to receive access to exclusive offers. %PDF-1.3 We know the equipment AND service end of the emissions industry! One line is attached before the DPF. Can anyone advise on what the typical DPF Sensor readings in mbar would be in the following situations..? Has this been figured out, I'm almost due for a test and not interested in finding and swapping out the exhaust. In an analogue way the upper range 4.8V5.0V is also reserved for sensor diagnosis. We had two dpf faults on our 2012 3.0 180 one when it was 6 months old they fitted a new sensor (or ceramic capacitor) thier words, it failed again after 4 years a new type of sensor was then fitted with new wiring and pipes by the Fiat dealer at a cost of 240 job done.
