Replace your DPF sensor, that failing sensor will cause failed regens and will also keep kicking it into limp mode. Page 3 AS, S.L.U. Part NO. 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. 6 0 obj They should not be damaged or plugged.
