Help Help Help!!!!
Hey Guys I was driving my truck today (99.5 F250 7.3) and as i shifted into 4th gear and started going the truck made a loud pop noise and then lost almost all power. It acts as if its bogged down. There is no spooling up of the turbo or anything any help would be great. I read the codes and got P1248 Turbo Boost Pressure Not Detected, P1280 ICP Circuit Out of Range Low, and P1670 EF Feedback Signal Not Detected. any help would be great thanks.

There on both ends of the intercooler tubes. They go into the intercooler and the tube, and from the intercooler tube to the 5 way spider in front of the turbo. Mine are blue, but they may vary by year.
