Diesel emissions systems rely on sensors to send signals to control modules when maintenance on the aftertreatment systems is required or when something is no longer functioning properly and requires a repair. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. 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. . Product Benefits: Quality Control Cost Effectiveness High System Accuracy . This website uses cookies to improve your experience while you navigate through the website. Free shipping. It is also possible to check your DPF differential-pressure reading with a multimeter. I just replaced the DPF with a refurbished one and the code comes back even though the new one is in good shape.

I can't live with the van as it is 08 . Of course I would change the oil again . These are signs that the DPF sensor is dying, and the DPF may not correctly regenerate. 2020 Ram 3500, CM SK flat bed. The cookies is used to store the user consent for the cookies in the category "Necessary". The voltage should read a value between the pressure values of both hoses. This keeps this site running and allows me to keep creating content. It's important to rev the engine and check for voltage changes before testing anything else. 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.

In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. Inspect the DPF differential pressure sensor tubes. use a multimeter and vacuum pump to test the pressure and voltage readings. 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] To find which wires are being used for each signal in your car, consult the manual. Next Post . Knowing what good figures are will be a great help. Free shipping for many products!

Typically, the ground port is the leftmost or rightmost prong but it may vary depending on the sensor you have. Your exhaust gas flow at idle is not very restricted by your DPF even when mostly clogged. 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. 23.65. However, it is usually mounted on the aftertreatment assembly with a heat shield to protect it from heat or in the engine compartment again to protect it from the heat generated by the diesel emissions system. Electrical sensors in an engine have wires to the ECU that can be damaged from road vibrations or crack and melt from extreme heat. :$:High tech old school and finally lovin it. Keep your vehicle turned off while you remove the pressure sensor. 4 0 obj
SKU: 904-7127 : Quantity: Share. Operating conditions: The engine spends too much time on light load conditions, causing insufficient DPF temperatures which prevent passive regeneration to take place. Sometimes the DPF is misdiagnosed as the problem and replaced only to quickly fail again because the sensor is the actual issue. They should not be damaged or plugged. Engine misfire: 1654, 1655, 1656, 1657, 1658, 1659 Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. Black - Diesel DPF Particulate Filter . I had a conditional pass but only aloud that one time, now need to fool it or return to stock. If you want to check the sensor while its still attached to your vehicle, use a multimeter and vacuum pump to test the pressure and voltage readings. However, replacing the DPFE sensor is a simple task that can be done with a few everyday tools. 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 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. During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. For a better experience, please enable JavaScript in your browser before proceeding. Important to note: The vehicle or machine manufacturer is responsible to construct the wiring harness and allow the sensor to eventually connect to the ECM. F40Model Year: 2019 + . Run the engine on high idle without load (around 1600 rpm) for about 10 minutes to warm up the aftertreatment. % of people told us that this article helped them. 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.

When you purchase through links on our site, we may earn an affiliate commission, which supports our community. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. In this manner, the sensor is able to determine the pressure difference across the DPF, which serves as the primary input data the PCM uses to determine the soot load, and therefore, the efficiency of the DPF. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. My understanding is that the 40420 does not have DPF delete capabilities. 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. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Also Mike, I do not idle it very long at all . If you notice the numbers changing on the multimeter display, then the sensor has electrical resistance, meaning a current can pass through it and it will still work in your vehicle. Soot load is estimated by the ECM, by monitoring the inlet and outlet pressure of the filter. Assuming that you validated your repair after each step that youpreviously followed (run engine, test drive etc): If fault code 1922 is still active OR inactive with more than one counts in the last 25 operating hours, the DPF is fully clogged. %
