2006 Freightliner CL120 with a detroit 14.0 EGR engine. Truck came in smoking white and losing power. Changed EGR Valve AND PLUG, changed turbo. Truck will not go over 1600 rpm, has codes as of 2 hours ago inactive for Flas Code 44,83,83,44,49,51,39. Truck has an ultrashift transmission and will not even shift into 3rd gear automatically.
update: took air hose off cold side and changed intake boost sensor and truck runs over 1500rpm no problem, but lots and lots of black smoke clears after few seconds of mashing the accelerator down, doesnt isnt sputtering
sorry, black smoke... all of a sudden again it wont go over 1500-1600 rpm... changed delta p, turbo, egr valve, v-pod... really strange problem. ran strong and hard after we changed the boost sensor but smoked lots of black again and then changed delta p and no smoke but no longer over 1500-1600 rpm...
no leaks, truck had an inframe 30k miles ago, figured out the rpm problem (egr valve plug wires were crossed) now only problem is any time u hard accelerate you get a good 3 seconds of black smoke then it clears if u let off accelerator then mash again same thing, as many times as u do it
newest recent codes are both for TCI Temp
