\u00a9 2023 wikiHow, Inc. All rights reserved. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. The code DOES NOT mean that the DPF needs to be replaced immediately. Category: Exhaust Pressure Sensor / DPF 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 An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicle's exhaust before and after it passes through a filter. Locate the EGR differential pressure sensor (next to the EGR valve), remove the screws and perform a visual check on its pressure ports.

Industrial differential sensors may be integrated into a standardised fitting, allowing it to be built into existing pipework. P r e p a r a t o r y S t e p s WA R N I N G Batteries can emit explosive gases. % of people told us that this article helped them. P2453 - Diesel Particulate Filter Pressure Sensor "A" Circuit Range DPF differential pressure sensor - Sensors Why do they fail? New OEM Genuine Cummins Temperature Sensor 4954574. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). If you replaced the assembly, validate your repair and then proceed to the next step. If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. now are you positive resistors cant be used in the DPF sensor? It is not easy to miss there are two flexible pipes connected on the sensor body. 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? Cummins Differential Pressure Sensor 5492073 I loved it. Does anyone know what "normal" reading should be? These are signs that the DPF sensor is dying, and the DPF may not correctly regenerate. Figure 1 is a schematic of this sampling apparatus. I would think if it was not burnt and had good contacts it should be just fine but instead so many guys just change it out ! the difference between the two measuring points. . If not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). Cummins ISX CM871 Regen Temps Question - TruckersReport Diesel Oxidation Catalyst (DOC) faults: 3313, 3314, 3315, Faults that could be causing excessive soot generation, Fuel System faults: 559, 1139, 1141, 1142, 1143, 1144, 1145, ,4713 thanks, Frank. Last Updated: April 6, 2020 An air leak would change the sensor readings, thus resulting in the code. Free shipping.

Wiring harness: Incorrect wiring harness pin installation. DPF Differential Pressure Sensor Testing MiracleMAX - YouTube It does not store any personal data. Make sure the battery voltage is about 12.6 volts. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. To protect the engine, the ECM activates the power derate. 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 the DPF has already been replaced during the repair (eg. Using DDDL go to service routines> SCR & DPF voltages. F40Model Year: 2019 + . If the sensor values on step 5 meet specifications, it is necessary to check the sensor voltage readings further. 8C3A9G824AB 137423 C17G2807851 8C3Z9J460D 0741584Z03 1778137 . DPF differential pressure sensor signal stuck-in-range. stream Some product links are affiliate links which means if you buy something we'll receive a small commission. Avoid removing both hoses from the pressure sensor since you wont produce accurate results. The cookie is used to store the user consent for the cookies in the category "Performance". Next Post . Connect your preferred diagnostic tool, read and list all other active fault codes OR inactive fault codes with more than one counts in the last 25 operating hours. Here ya go, using the search function for this thread,, I have the three 100 OHM sims used for the DPF; Used very little until I went with EFI live, a couple of years ago. Has this been figured out, I'm almost due for a test and not interested in finding and swapping out the exhaust. You can buy metal T-pins from hardware stores or online. 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. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.

Diesel Particulate Filter (DPF) Pressure Sensors . These cookies ensure basic functionalities and security features of the website, anonymously. If the signal is indeed out of specifications, replace the sensor. How To Test DPF Differential Pressure Sensor. Diagnostic The differential pressure sensor measures the pressure drop between two points in the flow pattern and is used at two different points in the exhaust manifold. 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. 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. Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 Figure 5.1 Correlating pressure signals to determine DPF transfer function The ISX CM871 was a big deal, as this is the first year Cummins started to place diesel particulate filters (DPFs) in commercial trucks. I'd like to get the GDE tune and am also considering deleting the DPF because I want a reliable van that doesn't leave me stranded hours from home on a regular basis. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. NEW Genuine Cummins OEM differential pressure sensor 4384138. Differential pressure switches that are out of calibration have a tendency exponential the further up the scale you go. 2 0 obj The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. 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! This means that the DPF Outlet sensor is reading high due to a restriction in the exhaust or faulty sensor Was it the outlet sensor you changed? The parts tend to make up the majority of the cost, usually between $100 and $400, while the labor might only be $50 to $100. Brand: LAPB 4 ratings $13000 FREE Returns About this item Original DFN Pressure sensor for Cummins We offer 12 Month warranty on this part. When diesel particulate matter blocks one or both of these airways to the sensor, the sensor can no longer accurately determine pressure changes, which can result in catastrophic damage to the DPF and ultimately the engine. 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. %PDF-1.3 This image may not be used by other entities without the express written consent of wikiHow, Inc.
