Where should you buy your replacement DPF sensor should it need to be replaced? now are you positive resistors cant be used in the DPF sensor? 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. Soot load is estimated by the ECM, by monitoring the inlet and outlet pressure of the filter. Following verification, proceed to the next steps. This filter traps particulate matter (also called "soot") created by the engine. 4954574 Genuine Cummins OEM NOX Inlet Temperature Sensor, New In Box, DPF Sensor.
