These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. We will create 2 new fault codes related to the DPF differential pressure sensor to check if the ECM detects the new conditions. Here's how to test the DPF. The ECM will set the fault if it detects that the aftertreatment diesel particulate filter is not present in the aftertreatment/exhaust system. Has this been figured out, I'm almost due for a test and not interested in finding and swapping out the exhaust. 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. One line is attached before the DPF. Cummins DPF Differential Pressure Sensor - 2871960. Opt for a digital multimeter since they can perform multiple functions and will be easier to read while testing the sensor. DPF differential pressure sensor tubes to achieve a 010 degree sensor tube downward angle. The signal output is described by a linear function: U = (0.82 x p +10) x 0.05 [V/kPa] Where: U = signal output voltage [V] DC p = differential pressure [kPa] Entdecke DPF Exhaust Differential Pressure Sensor For International Navistar 3626432C1 in groer Auswahl Vergleichen Angebote und Preise Online kaufen bei eBay Kostenlose Lieferung fr viele Artikel! Disconnect the DPF pressure sensor connector. DPF Differential Pressure Sensor - Consensus. Also Mike, I do not idle it very long at all . At the other point it is used to control the low-pressure exhaust gas recirculation. GiU#5.R ^1Vq7W~w:5|g*?,LUUsiB,}c" 6#va\lg? Wiring harness: Incorrect wiring harness pin installation. New Cummins DPF Differential Pressure Sensor 2010-16 PN 2871960 904-7127 w/Tube. Last regen was about 900 kms ago. Free shipping for many products! A Diesel particulate filter helps to trap dust and other debris that might otherwise cause the pressure to rise in your diesel engine. A diesel particulate filter (DPF) differential pressure sensor measures exhaust backpressure and signals when the power-train control module (PCM) should begin a regeneration process to clear the filter of diesel particulate matter (DPM), or soot.

Pc#V. Here ya go, using the search function for this thread,, I have the three 100 OHM sims used for the DPF; Used very little until I went with EFI live, a couple of years ago. If your signal values do not meet specifications, check once more to ensure you are doing this correctly. Engines that operate longer periods on light loads (eg. The cookie is used to store the user consent for the cookies in the category "Analytics". Vacuum pumps measure how much pressure builds up inside the sensor when you add more air. The sensor monitors and measures the pressure with the EGR valve. whether or not its possible id definitely appreciate any help as i dont know about resistors and would definitely like to try this out was thinking of wiring up something to a set of switches that when flipped it will progressively fool the sensor into thinking the filter is actively cleaning or becoming blocked.

The two pipes allow exhaust gas pressure from the inlet and outlet of the DPF respectively to reach the sensor. There are 251 fault codes for this engine line. 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. Connect your diagnostic tool and monitor the DPF differential pressure sensor voltage (engine NOT running). Connect your preferred diagnostic tool, read and list all other active fault codes OR inactive fault codes with more than one counts in the last 25 operating hours. For a better experience, please enable JavaScript in your browser before proceeding. If not, check the wiring harness for continuity and correct resistance (less than 10 Ohms). That's the point behind controlling the map designated for the post injection responsible for the added heat and fuel for regeneration. This cookie is set by GDPR Cookie Consent plugin. I would always suggest to use a tool such as Cummins Insite or TEXA (you can even rent one from Diesel Laptops). Check my guide on how to create an account or my training courses on how to use QuickServe Online effectively. 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. As I increase rpm to 2000 rpm (parked), back pressure increases to approximately 2000 hpa, and differential . Keep your vehicle turned off while youre plugging in the pins so you dont risk getting shocked. Thank you in advance for your support!

Also check for pin-to-pin short circuits. check wiring diagram). 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. Already tried 2, but thank you all the same. In the most extreme cases, a DPF failing can create an environment where the exhaust gas can not be fully purged. In other words the higher the differential the faster it goes up the scale. Not yet, i dont want to keep doing them. Exhaust Pressure Sensor 3921027401; I've got a long experience as technical trainer and training course developer. Check if the signal of the aftertreatment temperature sensors is within specifications.

The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. Be careful in removing the sensor and hoses, as there are other sensors in this area that can be easily damaged. Monitor DOC inlet pressure sensor voltage pin 87. This enables the diesel particulate filter to remove more contaminants from the system and keep your diesel emission system working properly. Turn on the ignition switch without starting the engine. This leftover diesel fuel can wash away the oil film that protects internal engine components and can cause catastrophic failure.
