This can be closed up and deleted whenever, my dad ended up having the DPFE replaced and was charged out the *** to do so. The bill was as follows:
$100 to scan for the code(P0401, which I told the guy)
$90 for 1 hour of labor(It took him an hour to do a swap, I doubt that)
$170 and change for the DPFE itself...(I was going to get a brand new one for $50, but I guess $170 works too)
