Differential Pressure Sensor (DPS) - Exhaust Pressure Sensor - RPF Pressure Sensor In the exhaust system of your vehicle, the differential pressure sensor measures the pressure upstream and downstream of the diesel particulate filter, i.e. By signing up you are agreeing to receive emails according to our privacy policy. Following verification, proceed to the next steps. If the aftertreatment DPF differential pressure sensor voltage readings are not within specification, then a malfunctioning aftertreatment DPF differential pressure sensor has been detected. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. The pipes are then connected to the system where the measurement is to be made. I don't see anything in the factory service manual that describes what the values should be.

If you dont get any reading on your multimeter, make sure youre holding the probes against the correct pins. if i can manipulate the DPF sensor to try and control and fool the ecm into thinking the regen cycle is working and complete it i can then have a deleted truck that will pass obd2 emissions. To reduce the possibility of personal injury, always ventilate the compartment before servicing the . 6 0 obj Diesel Particulate Filter (DPF) Pressure Sensors . 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. The online store you use should provide you with access to industry experts to help you if you run into an unexpected problem changing the sensor. for example on a deleted truck that the aftertreatment system hasnt been disabled only codes shut off, the truck will want to go into a timed/forced regen even though there is no DPF.

Include your email address to get a message when this question is answered. the difference between the two measuring points. 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. DPF Differential pressure sensor circuit function The ECM constantly monitors the soot load of the DPF. Pressure Differential in DPF - 138 hPa. endobj At one point it reports the charge status of the particle filter and monitors its function. The sensor hoses can become clogged from soot in the exhaust system just like the DPF.

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. Monitor these parameters during a regen, and you should have these values; EGR differential pressure - less than 0.5" Hg - if higher, could be stuck open/leaking EGR valve EGR valve position - 0% - EGR valve must be closed.

The cookies is used to store the user consent for the cookies in the category "Necessary". "I started off looking how to test the pressure sensor. If the aftertreatment DPF differential pressure sensor signal voltage does n o t meet specification, replace the aftertreatment DPF differential pressure sensor. 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. If you replaced the assembly, validate your repair and then proceed to the next step. I wish that would have been stated in the instructions from PPEI when I did the delete. We are also having troubles with dpf sensor. Steps. Once the test is completed, record the results and follow the instructions on the diagnostic tool. Before you change the DPF sensor, determine if the DPF pressure sensor needs to be replaced, or if carbon cleaning will get it operational. EGR differential pressure faults: 1866, 2273, 2274. For many years, operators of commercial trucks have been trying to increase uptime and minimize unscheduled and costly roadside repair events. 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. Already tried 2, but thank you all the same. You get a considerable pressure drop (offset) with a high flow in a restricted passage, while it tends towards zero with a smaller flow. New OEM Genuine Cummins Temperature Sensor 4954574. I listed the most important troubleshooting steps below. Wiring harness: Incorrect wiring harness pin installation.

Why do so many guys on this forum change the Y-cable ? $69.00. Of course I would change the oil again . 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 pressure sensor location is a bit different for each make and model. Product Introduction. 2022/3500/6.7/68RFE/Crew C/SB/SRW/TRXOFFROAD Decals/Tradesman/4X4/FRTRPLBPR/TOOLBOX/RCHTRK/ 275 MTR's KEVLAR/ 2" leveling kit Front/1" rear/Metal Grid Protec. Does anyone know what "normal" reading should be? 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. If the air filter is restricted, it could affect the air/fuel ratio causing excessive soot generation. 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.
