Exhaust Pressure Sensor 3921027401; Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. One sensor that keeps an Eagle Eye on the condition of the DPF is the Differential Pressure Sensor.How can we test this sensor and how can we be sure that the ECU is processing what it sees? Make sure the battery voltage is about 12.6 volts. During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). one on each side of the DPF, and it takes a reading of the pressure differential between the two. Proceed to check the condition of the ports on the EGR mass mesurement flow assembly. The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. P2454 Chevrolet Diesel Particulate Filter Differential Pressure Sensor Circuit Low Voltage. I disconnected the exhaust outlet and ran a snap test and found no smoke exiting the engine. Knowing what good figures are will be a great help. . The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter.

Following verification, proceed to the next steps. We are also having troubles with dpf sensor. During passive regeneration, soot is burned-off from the inlet of the filter and extend its service life. The vehicle then ran fine for about 197km then the background regens kicked in (no light on dash) and these were occurring every 1-16km according to Multiecuscan, which is when I get white smoke bellowing . Just in case anyone's searching for the values, MES is showing the following:-. The sensor is located on the Aftertreatment system, mounted directly on the DPF. Of course I would change the oil again . Baking that style of filter isn't always a sure thing because of the way it's build. my thoughts like i said were to manipulate the DPF sensor in a way that it would send the appropriate signals to the ECM telling that it is in This image may not be used by other entities without the express written consent of wikiHow, Inc.

Hi I got the autel 802 code reader and it gives exhaust back pressure and DPF differential pressure. The sensor hoses can become clogged from soot in the exhaust system just like the DPF. Last Updated: April 6, 2020 . 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? For a better experience, please enable JavaScript in your browser before proceeding. I have a spare sensor I can send to you, you could install it as a test to eliminate your "new" one..?

Always work outdoors or in a well-ventilated space when running your vehicle to prevent harmful fumes from building up. At the other point it is used to control the low-pressure exhaust gas recirculation. 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.
