P1405 OBDII code

[crt1583]

I was driving my truck about a week ago and hear loud hissing coming from under my hood, pulled over and noticed the two hoses popped off hte DPFE sensor. Replaced with two brand new oem spec hoses. Drove the truck hoses popped off again, so i placed tie starps on the hoses to act as a clamp. Truck has no power at take off take sbout 2 miles to get up to 55 mph and the rpms sound very high but tach show it to not go over 2000 rpms and now the codes in the pcm are p0175 too rick bank 2, p0171 too lean bank 1, p306 cyl 6 misfire and p1405 dpfe hose off detected. Spark plug was changed CEL was reset.
This is really stomping me any advise.

WTF!!!!!!!!!

Possible bad DPFE? Or have you fixed it already. Please post the fix for others.

There shouldn't be that much pressure at the dpfe hoses. Check for exhaust restrictions such as bent pipe or plugged cats. Unscrew the o2 sensors and let them hang for a short test drive. If the cats are plugged the difference in power will be obvious
