Figure 1 is a schematic of this sampling apparatus. 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? The sensor performs the following simple mathematical function: DPF Pressure Difference = [DPF inlet pressure] [DPF Outlet pressure]. 3 0 obj This image may not be used by other entities without the express written consent of wikiHow, Inc.

Exhaust gas pressure - 120-150" Hg - Low could indicate a failing turbo. 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. capacity of 0.250 L of air/min; (4) a pressure transducer capable of measuring to 0.1 in. Cummins Exhaust Temperature Sensor OEM 4954574. 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. I'd like to get the GDE tune and am also considering deleting the DPF because I want a reliable van that doesn't leave me stranded hours from home on a regular basis. Guys, my MD802 is telling me that the DPF is too clogged to regen so I'm assuming that it can only be cleaned by taking it out and manualy cleaning it , chemical or roding it out ?? At one point it reports the charge status of the particle filter and monitors its function. By using our site, you agree to our. To protect the engine, the ECM activates the power derate.

JD. 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? Also check for pin-to-pin short circuits. Send email to us. Avoid removing both hoses from the pressure sensor since you wont produce accurate results. Product Introduction. A forum community dedicated to Dodge Cummins Diesel truck owners and enthusiasts. By comparing the pressure at these two points, the sensor can track the buildup of soot within the DPF and trigger the PCM to do a regeneration cycle at the appropriate time.

This cookie is set by GDPR Cookie Consent plugin. If we can find it, we should be able to cut post inject to next to nothing where as when the regen is initiated there is actually nothing happening externally but you are telling the ECM that is is happening and it's happy. As shown here, the sensor monitors the exhaust pressure at both the upstream inlet and downstream outlet of the DPF. 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. Engine problems: If the engine has malfunctioned, it is possible that excessive soot is created, causing the DPF to get blocked. In theory, theory and practice are the same.
