Using DDDL go to service routines> SCR & DPF voltages. 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. Locate the EGR differential pressure sensor (next to the EGR valve), remove the screws and perform a visual check on its pressure ports. The Differential Pressure Feedback Exhaust Sensor, or DPFE sensor, is part of the vehicle's exhaust gas recirculation (EGR) system. 6 0 obj Short the +5V SUPPLY pin to the Differential Pressure SIGNAL pin (NOT the outlet pressure signal pin! Monitor DOC inlet pressure sensor voltage pin 87.

At ambient temperature26C (78F) and above:Voltage reading should be between 0.642 and 0.738 Volts. However, it is usually mounted on the aftertreatment assembly with a heat shield to protect it from heat or in the engine compartment again to protect it from the heat generated by the diesel emissions system. 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. Cummins provides sensors that support a multitude of critical components on your engine - from controlling the speed of the turbocharger to assisting the level of NOx taken into the aftertreatment system.

The two pipes allow exhaust gas pressure from the inlet and outlet of the DPF respectively to reach the sensor. Otherwise issues like you describe will occur. If this happens, the DPF can become contaminated and eventually fail. However at higher rpm and load, things start to get crowded and that's where you'll see a difference. If you notice the numbers changing on the multimeter display, then the sensor has electrical resistance, meaning a current can pass through it and it will still work in your vehicle. Check out my diagnostic tool suggestions! if it was fully clogged), then proceed to step 9. I have same scanner and love it. Since half of the channels are plugged at the front of the DPF and the other half are plugged at the back of the filter, only half of the filter channels accumulate soot or ash.
