Message: [QUOTE="Powerstroke1098, post: 1410717, member: 13212"] Here's an update for anyone with the same issue. So I've been working with an open checkbook on a friends completely hammered 11' 6.7 work truck for a few hours after work everyday, slowly fixing a long long list of issues to make it 100%. The truck has 145 thousand hard miles of plowing and towing. Its had a CEL and been under reduced power for two years and had a code for just about every emissions related component, yet he worked it every day. So on top of many other things I just d****** and T**** it. Afterwards I noticed it didn't have that hawk noise that every 6.7 has when the VGT vanes open, but it didn't have a code at the time and I was unsure if it was because he broke the passenger mirror off and replaced it with a cheap one with no ambient air temp sensor so the truck thought it was -40 outside, I also hoping that was the case as to not add another issue to the list. Anyway, I drove it to lunch and it went into limp mode and threw a p132a code, cleared it and it came right back and did the same thing, it also it clearly didn't spool down low like a healthy 6.7. I checked voltage on Pin 1 at the waste gate solenoid connector on the harness side which shares the same supply voltage as the VGT actuator and it had battery voltage with the KOEO like it should, however Pin 2 at the VGT actuator on the harness side didn't with the KOEO so I knew there was an open between S110 and C1390. In the WSM it said S110 was near C1181 (#1 injector) so I took the passenger fender liner out and the fuel rail cover off and it turns out the A/C compressor to condenser discharge line chaffed through the fuel rail cover and through the harness on the RH cylinder head and took out the VT/BN supply voltage wire to the VGT actuator. So if anyone has the same issue check there first so you don't have to go through the trouble. To make matters worse I also noticed one of the legs on the #4 injector hold down was broken off, so i'll have to go through and check how many others need to be replaced tomorrow lol. I attached a wiring diagram below and circled the connectors and the splice I was talking about. I apologize for the lengthy post, just hope it can help someone. [/QUOTE]
