Today's and tonight's Amsterdam, North Holland, Netherlands weather forecast, weather conditions and Doppler radar from The Weather Channel and Weather.com 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. my thoughts like i said were to manipulate the DPF sensor in a way that it would send the appropriate signals to the ECM telling that it is in Last regen was about 900 kms ago. High Class Service Truck. The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. It's going to want to close turbo down and open EGR valve until it see pressure Take the butterfly out of the throttle and leave EGR in place but blocked off with plates Then setup another resistant mosfet to simulate a pressure in the EGR to keep that readiness monitor happy. While there seems to be benefits to these computer managed engines, they bring a list of problems as well.

First, check your Cummins DPF Differential Pressure (DPF) Sensor Reading. Active and stationary regeneration of the DPF will be disabled. They worked, but I had the CEL. 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. Industrial differential sensors may be integrated into a standardised fitting, allowing it to be built into existing pipework. Connect your diagnostic tool and monitor the fault code page. The voltage should read a value between the pressure values of both hoses. Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. 4 0 obj 2020 Ram 3500, CM SK flat bed.

If the difference exceeds 24oC (43oF), replace the temperature sensor module assembly (the 3 temperature sensors are connected on the same CAN-BUS module and cannot be replaced separately, or be repaired. Appreciate 0 Quote . ARghh.. Not again.. Can anyone advise on what the typical DPF Sensor readings in mbar would be in the following situations..? 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? It will need to either be removed, professionally cleaned, or replaced, both options being much more than the cost of diagnosing and replacing a faulty sensor. Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. If you have any of the following fault codes active, troubleshoot them first: Related to aftertreatment regeneration: 2777, 4213, 6416 The two pipes allow exhaust gas pressure from the inlet and outlet of the DPF respectively to reach the sensor. Covers all these components including mounting hardware and gaskets: Complete Aftertreatment System (DPF and SCR System) Aftertreatment Differential Pressure Sensor Body and Mounting Hardware; Aftertreatment Fuel Pressure Sensor O-Ring; Aftertreatment Fuel Pressure Sensor Body Solving a blocked DPF by unblocking it, may lead to it blocking again.

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). Just like any other filter, these must be maintained and eventually replaced - at great expense! "I started off looking how to test the pressure sensor. Otherwise, you can remove the sensor and test the electrical resistance between the ports. I have same scanner and love it.
