Cummins Dpf Differential Pressure Sensor Reading If you are working in a diesel engine, then you know how important it is for the engine to have a good diesel particulate filter. 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. When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. 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. If voltage is NOT between 0.44-0.56 volts replace the DOC inlet pressure sensor.

The correct oil is hard to find and spendy . for example a resistor that will give it a signal showing that the DPF is actively being "cleaned" ? Monitor DPF outlet pressure sensor voltage pin . If I understand it correctly, this value is a discrepancy in the readings between the two sides of the sensor that the ECU learns and compensates for. At one point it reports the charge status of the particle filter and monitors its function. Check out my diagnostic tool suggestions! 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 the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. If you've checked both of the above, then it's time to remove that DPF filter and have it cleaned and checked. Ram Cummins with lots-o-mods. To test if your battery is working properly, you'll need to connect the multimeter ground with one lead connected directly onto its negative terminal and run a quick "plausibility" check. When this happens it creates all kinds of problems for the truck operator and the fleet.

Some posts may contain affiliate links. Clean or replace as necessary. 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? The multimeter should normally display a voltage between 4.5 to 5 volts for referencing the 5-volt, a solid 0 volts for the ground wire, and anywhere between 0.5 and 4.5 volts for the signal wire. The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. Short the +5V SUPPLY pin to the Differential Pressure SIGNAL pin (NOT the outlet pressure signal pin! National Truck Parts has a large selection DPF and emissions products for heavy duty trucks. Level up your tech skills and stay ahead of the curve. Category: Exhaust Pressure Sensor / DPF Sensor. Otherwise issues like you describe will occur. Otherwise, connect your diagnostic tool and read the fault codes. The DPF differential pressure sensor is a different sensor that is necessary for filtration to function effectively. DPFPartsDirect.com meets all these qualifications. If you still dont get a reading, then there may be a problem with your vehicles electrical system. 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. The DPF sensor measures the pressure drop across a DPF. This image may not be used by other entities without the express written consent of wikiHow, Inc.

During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. It may not display this or other websites correctly. If cleaning the soot and other carbon deposits from the sensor and hoses dont work, or if the sensor is melted or cracked, it needs to be replaced. The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. Where should you buy your replacement DPF sensor should it need to be replaced? Engine problems: If the engine has malfunctioned, it is possible that excessive soot is created, causing the DPF to get blocked. 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. correctly.

The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter. 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? C - P244B CausedFrom a Full DPF. Receive the latest updates on new posts, freebies and training courses. Once you remove the guts from the DPF, you will end up with a check engine light and the engine will eventually go into De-Rate. Solving a blocked DPF by unblocking it, may lead to it blocking again. But.even if you know the pressure how do you propose measuring it. Lack of boost also causes excessive soot. Adding another set of data-points from a 2007 3500 with recent recurring, key-cycle resettable LHM issues and a 2626-1 DTC as shown on my new MD802 scanner: Exhaust Back Pressure at idle - 1517 hPa. 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 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. I've got a long experience as technical trainer and training course developer. Well I just replaced the DPF differential pressure sensor and cleared the codes, however two codes came back .
