I have posted the problems with my truck over the last couple of days and received a lot of help. Thanks guys. I'm going to go and get the uvc harnesses today and do the job myself and I'm just reveiwing all of the posts and replies to make sure that I'm not missing something.
This is the trouble code (0475) that my hypertch programer is giving me at this point. Yesterday, I took the performance program out of the truck and tthe DTC codes were 1249, 1211, 1316, 0475. The truck ran so bad that I had to put it back in just to drive it to the shop. DIESELMANN (senior ford diesel tech) Said 1249, 1211 were from the performance program. 1316 indicated the injector circuit and said to replace my uvc harness.
When I reinstalled the program the only DTC code was 0475. What it it?
Exhaust Pressure Control Valve Malfunction
Exhaust Back Pressure Regulator
possible causes:
--shorted to power
--open/grounded circuit
--damaged solenoid
--damaged PCM
