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. 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. To protect the engine, the ECM activates the power derate. 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! The test runs for 30 to 60 minutes approximately. correctly. Ok so in the last 5 min I made something work, using a MOSFET tied into a resistor representing the max resistance that we need to see for the EGTs, I can use the mosfet to ramp the resistance from OL al the way down to the 5ohm resistor at 5vdc, it works and I can step it in .003 ohm resolution. You just pull the 2 rubber hoses off. Replace the sensor. "I started off looking how to test the pressure sensor. Categories .

If you still cant find the pressure sensor in your vehicle, take your vehicle to a mechanic since the sensor may be built into the pipes. Product Description. If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. In other words the higher the differential the faster it goes up the scale. The code DOES NOT mean that the DPF needs to be replaced immediately. I take it you've tried a second static burn? The signal output is described by a linear function: U = (0.82 x p +10) x 0.05 [V/kPa] Where: U = signal output voltage [V] DC p = differential pressure [kPa] 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. !, 1946722 Genuine OEM . Keep your vehicle turned off while you remove the pressure sensor. one on each side of the DPF, and it takes a reading of the pressure differential between the two. 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. Fault codes 1879 and 3134 should become active. While there seems to be benefits to these computer managed engines, they bring a list of problems as well.
