If I'm correct the 410 code has t do with the EGR system check voltage on the connection of the DPFE SENSOR, you shoud have about 5 volts going in and about 3 volts coming out. had tha problem could not get to pass inspection till I decreased vacum to egr valve with small nail in line, after I did that my voltage came up to about 3 volts and the code cleared. Hope this helps
