My specialization is diesel engines and electronic management systems. a static regen after replacing the Dpf pressure sensor seemed to remove the Dpf warning light (it only came on after replacing the sensor). The DPF differential pressure sensor is located on the back of your car's engine compartment. Steps. Typically, the ground port is the leftmost or rightmost prong but it may vary depending on the sensor you have. I loved it. 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? Just like any other filter, these must be maintained and eventually replaced - at great expense! Thanks, Mike , but I'm trying to figure a way of rodding and chemicaly cleaning it . It's important to rev the engine and check for voltage changes before testing anything else. The voltage should read a value between the pressure values of both hoses. A standard pressure . Ash is stored in the DPF. The other is located after the DPF. endobj The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing. They should not be damaged or plugged. Otherwise, connect your diagnostic tool and read the fault codes. To reduce the possibility of personal injury, always ventilate the compartment before servicing the . http://www.cumminsforum.com/forum/6-7l-tech-articles/233548-egt-sim-basics.html. Have 3 litre fiat and as self servicing will need multiecuscan. While there seems to be benefits to these computer managed engines, they bring a list of problems as well. A differential pressure sensor is an electronic sensor that measures back pressure before and after the DPF and determines the level of soot contained within the DPF. When this happens it creates all kinds of problems for the truck operator and the fleet. Lack of boost also causes excessive soot. Without this sensor, the DPF would fill up with diesel particulate matter or soot and the truck would eventually be put into derate and would be restricted to limp mode which can be as little as 5 MPH. I can't live with the van as it is 08 . Make sure the battery voltage is about 12.6 volts. He has more than three years of experience writing for and working with wikiHow. New OEM Genuine Cummins Temperature Sensor 4954574. Free Postage. The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure].

You'll need a multimeter set to 20V and a pressure gauge to test it. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape. The DPF differential pressure sensor (DPS) has two pressure sample lines. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. The symptoms of a diesel particulate filter differential pressure sensor malfunction are not always easily detected because they mimic many of the symptoms of other components of the diesel emissions systems failing. Use a wire to see if the ports are free of soot all the way to allow pressure to reach the sensor. 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). If the sensor doesnt work properly, it could make your check engine light come on and cause the engine to hesitate or stumble.

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! Differential pressure switches that are out of calibration have a tendency exponential the further up the scale you go. stream This means that the DPF Outlet sensor is reading high due to a restriction in the exhaust or faulty sensor Was it the outlet sensor you changed? Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational. 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. If I understand it correctly, this value is a discrepancy in the readings between the two sides of the sensor that the ECU learns and compensates for.

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. You can also use an ohmmeter, which is similar to a multimeter but only measures electrical resistance. What to Look For in a DPF Differential Pressure Sensor That is Failing . If all's well on this end then it should show 12 volts or more when reading from the devices scale! ARghh.. Not again.. The correct oil is hard to find and spendy . Here's how to test the DPF. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Opt for a digital multimeter since they can perform multiple functions and will be easier to read while testing the sensor. 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. 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. If you dont get any reading on your multimeter, make sure youre holding the probes against the correct pins. I listed the most important troubleshooting steps below. Never attempted a regen works by resetting the time plug it in and wait about 10 seconds and crank. 99% Same Day Shipping - Multiple U.S. References. Ended up finding a lot more information I wanted to learn. JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. What is a DPF pressure sensor? How does a DPF pressure sensor work? Active and stationary regeneration of the DPF will be disabled. The DPF system is still used on commercial trucks today. The exhaust backpressure will build and with nowhere to go can end up back in the combustion chamber causing the soot to mix with the engine oil.

If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. thanks, Frank. We changed B28/8 sensor, check cables resistance to ECU = 0,7 OHMS all three cables, and check the two small tubes to dpf for leaking all good like new, made two regeneration and mark in Xentry as DPF has been renew and still problem come on after 50 km or less. The differential pressure sensor is one of the sensors in the diesel emissions system that communicates with ECU and the power-train control module (PCM) critical information about exhaust backpressure caused by the accumulation of diesel particulate matter (DPM) or soot.
