cummins dpf differential pressure sensor reading

The Pressure Differential Sensor on your 6.7L Cummins tells the ECM how "full" your DPF is. stream The more complex, the better! "I started off looking how to test the pressure sensor. Vacuum pumps measure how much pressure builds up inside the sensor when you add more air. If the difference exceeds 24oC (43oF), replace the temperature sensor module assembly (the 3 temperature sensors are connected on the same CAN-BUS module and cannot be replaced separately, or be repaired. PM me if you are interested. 23.65. Cummins ISB fault 1921 will no go inactive. - JustAnswer I played with my truck and found I can run the CMC tier3 ECM on my truck and everything runs like a champ, its only a 260hp tune at 3000rpm high idle but it worked working on how to bump max speed on that ECM with EFI Live as we speak. References. Figure 5.1 Correlating pressure signals to determine DPF transfer function This fault code sets when the DPF outlet pressure is greater than 30 kPa (4.2 psi) for more than 10 seconds. 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 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? Your multimeter may also be labeled with the letter V with 3 horizontal lines on top of it instead of DCV. 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. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website.
