The ECM constantly monitors the soot load of the DPF. 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. . 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. The diesel fuel that normally escapes through the exhaust system during the regeneration cycle only partially burns. x[G?Gr2FMOf$yD$Vd"k44vd/~o>{{O_/_|~xO}^w/U|?&yGY}\X7unrz3sTo&u|Ss5oqsCTmt^Z1%&M)foo7y'CenBQnZcu,f3Ouj`n814m7sya\9=b9sH3VD. Keep your vehicle turned off while you remove the pressure sensor. However at higher rpm and load, things start to get crowded and that's where you'll see a difference. 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. Figure 1 is a schematic of this sampling apparatus. If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 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. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. 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 ?? It's bad!!!!!! Will be replacing the Y-cable tomorrow, then re-testing. One line is attached before the DPF. The voltage should read a value between the pressure values of both hoses. %
Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 Electrical sensors in an engine have wires to the ECU that can be damaged from road vibrations or crack and melt from extreme heat. So if the front hose reads 1 PSI and the rear hose reads half PSI, the signal wire voltage should read somewhere around .8 volts. Cummins DPF Differential Pressure Sensor - 2871960. 4 0 obj
i know there are 4 levels that the DPF sensor will assume the filter is becoming blocked which will trigger a regen if i can find out what size resistors can be used to simulate that the filter is "cleaning" then maybe its possible to fool a deleted truck into thinking it successfully performed a regen? The 452A code is an information code only for BMW service to advise the customer that the DPF is approaching it's calculated end of life and they should make an appointment for a $4800 DPF replacement. Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. Analytical cookies are used to understand how visitors interact with the website.

Include your email address to get a message when this question is answered. Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). Engine and DPF Sensor Signal Based Methods 13 2.3.1. DPF differential pressure sensor signal voltage. Use a wire to see if the ports are free of soot all the way to allow pressure to reach the sensor. $125.00. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape. 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.

The sensor is connected to two hoses one upstream and one downstream from the diesel particulate filter. What to Look For in a DPF Differential Pressure Sensor That is Failing . The DPF differential pressure sensor is located on the back of your car's engine compartment. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. A Diesel particulate filter helps to trap dust and other debris that might otherwise cause the pressure to rise in your diesel engine.
