I have same scanner and love it. now are you positive resistors cant be used in the DPF sensor? The pipes are then connected to the system where the measurement is to be made. If everything passes a physical inspection and cleaning the sensor doesnt work, you can test the DPF sensors using a multimeter set to 20V and a pressure gauge. When diesel particulate matter blocks one or both of these airways to the sensor, the sensor can no longer accurately determine pressure changes, which can result in catastrophic damage to the DPF and ultimately the engine. thanks, Frank. DPF differential pressure sensor signal stuck-in-range. If the measured temperature difference is within specifications, proceed to the next step. Replace the sensor.

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. The differential pressure sensor on a diesel particulate filter (DPF) is used by the ECU to monitor backpressure and determine when regeneration is required to clear DPM or soot from the system. 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.
