Alright well I have a little black cloud that follows me every where I go! This kind of stuff only happens to me but hope to help someone else out! One of my trucks is a 2016 Ram 2500 Outdoorsman 4x4 6.4 Hemi. I have it leveled with 35x12.5/20 with 7100 miles on it. What happened to me might apply to everyone though.
I had just got back from a two week hunting trip and the following week my GF called me to say my truck went into Limp Mode! She shut it off ,started it back up and all was well. No problems for 4 days then it did it again. I pulled the codes both times with different codes showing at both times. I have a friend who is a tech at the Ram dealer where I bought my truck. So I brought it in and he suggested replacing the PCM ,had something to do with 5v ground wire. So he did and thought all was well , 2 days later my truck went into Limp Mode again with me driving it this time. A lightning bolt emblem came up on the 7 in. Cluster and threw more different codes. So I took it back to the dealer again. My friend kept it for 2 days and was texting me updates. He thought it was the Map sensor so he replaced it then would drive some and still would go into Limp Mode. He replaced every sensor that the computer kept telling him was the problem. He replaced every sensor on the truck,seriously. It was still going into Limp Mode!
Until finally he happened to notice while he was replacing the last sensor before we thought we were going to pursue Lemon Law! He saw that a heater hose clamp was positioned just a certain way so that it was cutting into my wiring harness. He said it was a billion to one that he saw it and that the clamp was wearing into the harness and was eating into the 5v ground wire. Seriously guys this kind of #*~< happens to me all the time. He mentioned the harness looked like it was to tight and was pressed up against the clamp. He had to open up the harness to see that the wire was bare and that it was the 5v ground. He isolated the wire and wrapped the harness also turning the clamp down away from the harness. He also repositioned the harness to have more slack. I am including pics but each pic might be a different post. I will also post this in the other forum for everyone to see.
