When this sensor is not working properly it compromises the regeneration process and will eventually lead to diesel emissions system failure. Also Mike, I do not idle it very long at all . Will be replacing the Y-cable tomorrow, then re-testing. What is a DPF differential pressure sensor? Otherwise, connect your diagnostic tool and read the fault codes. The DPF's differential pressure sensor reads a specific pressure that must be programmed into your ECU. % if not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). If you still cant find the pressure sensor in your vehicle, take your vehicle to a mechanic since the sensor may be built into the pipes. Not if you can take control of the regen fuel map, it's there just have to find it, I can adjust it on engineering level insite on off road engines, can adjust the fueling value and the timing from almost less than a trickle to 2000* EGT temps.. now you're thinking! 7.If needed, shorten the tubes to achieve a 0-10 degree sensor tube down angle. I would always suggest to use a tool such as Cummins Insite or TEXA (you can even rent one from Diesel Laptops). Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). OE / OEM NUMBER. If the DPF has already been replaced during the repair (eg. Find many great new & used options and get the best deals for Replacement Pressure Sensor DPF Black Differential For Cummins Plastic at the best online prices at eBay! Otherwise, you can remove the sensor and test the electrical resistance between the ports. The other is located after the DPF. We changed B28/8 sensor, check cables resistance to ECU = 0,7 OHMS all three cables, and check the two small tubes to dpf for leaking all good like new, made two regeneration and mark in Xentry as DPF has been renew and still problem come on after 50 km or less. There are 251 fault codes for this engine line. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. : WL-D05013.

Turn on the ignition switch without starting the engine. stream In other words the higher the differential the faster it goes up the scale. If everything passes a physical inspection and cleaning the sensor doesnt work, you can test the DPF sensors using a multimeter set to 20V and a pressure gauge. This filter traps particulate matter (also called "soot") created by the engine. Also check for pin-to-pin short circuits. 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. Fired her up and instantly got totally different readings with no error codes. P2454 Dodge Diesel Particulate Filter Pressure Sensor 'A' Circuit Low. Check my guide on how to create an account, training courses on how to use QuickServe Online effectively, you can even rent one from Diesel Laptops. 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. For this investigation, an SKC pocket pump with integral pressure transducer (SKC Inc., Eighty-Four, PA) was used to collect the . {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/90\/Test-an-Exhaust-Pressure-Sensor-Step-1.jpg\/v4-460px-Test-an-Exhaust-Pressure-Sensor-Step-1.jpg","bigUrl":"\/images\/thumb\/9\/90\/Test-an-Exhaust-Pressure-Sensor-Step-1.jpg\/aid11734221-v4-728px-Test-an-Exhaust-Pressure-Sensor-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

\u00a9 2023 wikiHow, Inc. All rights reserved. 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. PM me if you are interested. if it was fully clogged), then proceed to step 9. Consult OEM factory service information for the exact vehicle specs if needed. Industrial differential sensors may be integrated into a standardised fitting, allowing it to be built into existing pipework. 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. Ok so in the last 5 min I made something work, using a MOSFET tied into a resistor representing the max resistance that we need to see for the EGTs, I can use the mosfet to ramp the resistance from OL al the way down to the 5ohm resistor at 5vdc, it works and I can step it in .003 ohm resolution. capacity of 0.250 L of air/min; (4) a pressure transducer capable of measuring to 0.1 in. This leftover diesel fuel can wash away the oil film that protects internal engine components and can cause catastrophic failure. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash. Already tried 2, but thank you all the same. A Diesel particulate filter helps to trap dust and other debris that might otherwise cause the pressure to rise in your diesel engine. I've got a long experience as technical trainer and training course developer. If the aftertreatment DPF differential pressure sensor signal voltage does n o t meet specification, replace the aftertreatment DPF differential pressure sensor. $159.59. Well I just replaced the DPF differential pressure sensor and cleared the codes, however two codes came back .

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. It does not store any personal data. The voltage should read a value between the pressure values of both hoses. Monitor the temperature readings of the following sensors: The MAXIMUM difference between the sensor readings should be 24oC (43oF). They should not be damaged or plugged. Some posts may contain affiliate links. Hi I got the autel 802 code reader and it gives exhaust back pressure and DPF differential pressure. Intake throttle actuator faults: 175, 176, 177, 3539, 3541, 3542, 5879, 5881, 5882 Not yet, i dont want to keep doing them. Consult the wiring diagram and check the wires. The ECM activates the fault codes based on the measured pressure difference across the DPF. My understanding is that the 40420 does not have DPF delete capabilities. C - P244B CausedFrom a Full DPF. 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. http://www.cumminsforum.com/forum/6-7l-tech-articles/233548-egt-sim-basics.html. % of people told us that this article helped them. You can also use an ohmmeter, which is similar to a multimeter but only measures electrical resistance. If the sensor ports are clogged, clean them with brake cleaner or equivalent solvent. Basicly I'd have a V6 T1n .
