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.

This fault code sets when the DPF outlet pressure is greater than 30 kPa (4.2 psi) for more than 10 seconds. The ground and 5-volt reference should be identified first with their respective colored codes while backprobing any other signals that might need servicing. Last regen was about 900 kms ago. 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. While there seems to be benefits to these computer managed engines, they bring a list of problems as well. When the diesel particulate filter is not regenerating properly due to the faulty DPF sensor failing you may experience some of or all of the below symptoms: A DPF pressure sensor is necessary to keep the DPF free from diesel particulate matter and soot, and if the DPF is plugged, the regeneration process will not fix it. EGR differential pressure faults: 1866, 2273, 2274. 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.

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! This HAS to make a diff in how it runs though..theres no way it can run right without an accurate reading, can it? endobj
Naturally, a small pressure drop is always expected even on new DPFs, due to the fact that the exhaust gases are foreced to flow through the DPF walls. If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. I will see if I can make some raspberry PI or arduino code work and try to make a variable resistive output.

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). 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? JavaScript is disabled. Short the +5V SUPPLY pin to the Differential Pressure SIGNAL pin (NOT the outlet pressure signal pin! 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. Using DDDL go to service routines> SCR & DPF voltages. 180hpa at WOT. 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.

By comparing the pressure at these two points, the sensor can track the buildup of soot within the DPF and trigger the PCM to do a regeneration cycle at the appropriate time. A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot. Also check for pin-to-pin short circuits. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash.
