You can buy replacement sensors from auto parts stores and they usually cost around $100150 USD. If they are found to be damaged or plugged, replace or repair as necessary. Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning). 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. For a better experience, please enable JavaScript in your browser before proceeding. We are also having troubles with dpf sensor. If all's well on this end then it should show 12 volts or more when reading from the devices scale! In theory, theory and practice are the same. <>

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. 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. I understand part of the initials ie damp proof but what does the f mean. Not yet, i dont want to keep doing them. JD. Free shipping. Please use the following link when ever using Amazon.com. The Engine Control Module (ECM) uses the Exhaust Pressure Sensor to monitor the pressure differential through the aftertreatment Diesel Particulate Filter. 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. Share this: Twitter It is also possible to check your DPF differential-pressure reading with a multimeter. endobj
The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. EGR differential pressure faults: 1866, 2273, 2274. It is extremely frustrating when a work truck that is supposed to earn you money is unable to do what it is designed to do because a sensor has failed, and it is even worse when it breaks down and then requires a mobile mechanic and/or a tow to a repair shop to get it fixed and back on the road.

I had issues with mine so. http://www.cumminsforum.com/forum/6-7l-tech-articles/233548-egt-sim-basics.html. 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. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. It's important to rev the engine and check for voltage changes before testing anything else. This means that the DPF Outlet sensor is reading high due to a restriction in the exhaust or faulty sensor Was it the outlet sensor you changed? Keep your vehicle turned off while youre plugging in the pins so you dont risk getting shocked. Where should you buy your replacement DPF sensor should it need to be replaced? When this happens it creates all kinds of problems for the truck operator and the fleet. anyone know of what resistors can be used to fool the DPF sensor into thinking an active regen is working?
