This prevents the valve from malfunctioning and allowing too much exhaust into the intake manifold at one time. i also removed the hydrocarbon doser and cleaned that, along with cleaning the imap sensor, cleaning the egr differential ports and sensor, the exhaust back pressure sensor, and even replaced the exhaust pressure . Otherwise, you can remove the sensor and test the electrical resistance between the ports. 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. Active and stationary regeneration of the DPF will be disabled. Free delivery for many products!

When this happens it creates all kinds of problems for the truck operator and the fleet. 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? The DPF differential pressure sensor plays an important role in keeping the DPF functioning properly. DPF Differential Pressure Sensor - Consensus. Here is the link to the PDI tuner I have installed on my truck: https://www.amazon.com/dp/B087V9XWB7/?tag=ryannsophia-20Welcome to our channel! Fwiw I am getting 2500hpa back press and 90hpa dpf diff cruising on level ground. These diagnostic trouble code refer to the condition of the exhaust gas w4wn said: You need to leave the pressure sensor module connected to the wiring harness. Have all the electronic s if still. To protect the engine, the ECM activates the power derate. DPFs contain several hundred channels or cells per square inch (cpsi), with the most common being 200 cpsi. thanks, Frank. P2454 Dodge Diesel Particulate Filter Pressure Sensor 'A' Circuit Low. Free shipping. Where should you buy your replacement DPF sensor should it need to be replaced? During engine testing, the Cummins engineers have determined the allowed pressure difference levels on the DPF. The soot load of the Diesel Particulate Filter is monitored by the DPF differential pressure sensor. So if the front hose reads 1 PSI and the rear hose reads half PSI, the signal wire voltage should read somewhere around .8 volts. 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. DPF differential pressure: 1879, 1881, 1883 Typically, the engine operating conditions generate high temperatures and allow the passive regeneration of the DPF (self-cleaning).

We know the equipment AND service end of the emissions industry! endobj However, replacing the DPFE sensor is a simple task that can be done with a few everyday tools. New OEM Genuine Cummins Temperature Sensor 4954574. I don't see anything in the factory service manual that describes what the values should be. The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. :$:High tech old school and finally lovin it.
