If the sensor values on step 5 meet specifications, it is necessary to check the sensor voltage readings further. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. 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. The DPF differential pressure sensor can stop signaling to the PCM for regeneration. Fault codes 1881 and 3134 should become active. Damaged DPF. Knowing what good figures are will be a great help. Turbocharger faults: 1898, 2198, 2387, 2449, 2634, 2635, 2636, 3616 Avoid removing both hoses from the pressure sensor since you wont produce accurate results. If all's well on this end then it should show 12 volts or more when reading from the devices scale! Fwiw I am getting 2500hpa back press and 90hpa dpf diff cruising on level ground. You dont want to go to all the effort and spend valuable time and money replacing a sensor only to have it fail prematurely because it is a poor-quality replacement part. Sensors | Cummins Inc. If the soot load on the DPF is high, the ECM will activate the DPF system warning lamp on the dashboard. If you are wanting to be a little more accurate you can use an exhaust backpressure gauge that measures between 0-15 PSI. Where should you buy your replacement DPF sensor should it need to be replaced? Ash is stored in the DPF. Use channel exclusive promo code road3333 to get 12% off of your order today. In theory, theory and practice are the same. There are a lot of possible faults that could be triggering fault code 1922. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. <> We also use third-party cookies that help us analyze and understand how you use this website. if not, check the wiring harness for continuity and correct resistance (less than 10 Ohms).

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 Pressure Differential Sensor on your 6.7L Cummins tells the ECM how "full" your DPF is. You will never receive any spam from me. Differential Pressure Sensors | The Design Engineer's Guide - Avnet If the DPF has already been replaced during the repair (eg. Make sure the battery voltage is about 12.6 volts. 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? If you still dont get a reading, then there may be a problem with your vehicles electrical system. It does not store any personal data. 3251/0 EPA10 DPF pressure out of range, very high 2871960 | Cummins DPF Differential Pressure Sensor - National Truck Supply In an analogue way the upper range 4.8V5.0V is also reserved for sensor diagnosis. DPFPartsDirect.com meets all these qualifications. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. We had two dpf faults on our 2012 3.0 180 one when it was 6 months old they fitted a new sensor (or ceramic capacitor) thier words, it failed again after 4 years a new type of sensor was then fitted with new wiring and pipes by the Fiat dealer at a cost of 240 job done. I don't see anything in the factory service manual that describes what the values should be. P2454: Code Meaning, Causes, Symptoms, & Tech Notes - Engine-Codes.com PDF Fault Code: 1883 | SPN: 3251 | FMI: 2 - JustAnswer 23.65. I have same scanner and love it. 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. Fuel with a large percentage of sulfur will clog the DPF faster. Exhaust Pressure Sensor 3921027401; One line is attached before the DPF. Check out my diagnostic tool suggestions! Cummins Sensors provide a whole solution package, enabling system integration while meeting critical regulations. work was supported by Cummins Inc. and would not have been possible without the . endobj Part NO. DPF ash loading: Burned soot leaves ash behind. The DPF sensor measures the pressure drop across a DPF. The exhaust backpressure will build and with nowhere to go can end up back in the combustion chamber causing the soot to mix with the engine oil. Black - Diesel DPF Particulate Filter Differential Pressure Sensor For At the other point it is used to control the low-pressure exhaust gas recirculation. An air leak would change the sensor readings, thus resulting in the code. How does a DPF pressure sensor work? One of the major complications these suffer from is the DPF - the Diesel Particulate Filter. The operation of the Exhaust Gas Recirculation (EGR) valve will be disabled. This article was co-authored by wikiHow staff writer. 888.99.DIESEL. 180hpa at WOT. I'm in a similar position, my van keeps throwing the p242f code and sending the vehicle into LHM. capacity of 0.250 L of air/min; (4) a pressure transducer capable of measuring to 0.1 in. DPF Pressure Sensor Diesel Differential Filter For Cummins Particulate. Proceed to check the condition of the ports on the EGR mass mesurement flow assembly.
