LS XU5055 in limp mode most of the time

[DStoen]

Hello, We are going on almost one year and we still haven't got this tractor back to normal. I was ill for part of the year so it didn't get worked on very often. It is a 2014 LS XU5055 with 1168 hrs. It has been going into limp mode ever since it was new. It only di it occasionally at first but now it spends more time in limp mode then it does anything else. Needless to say I am quite tired of this and hope that someone can lead me to some resolve short of a fire! I have replaced the throttle electronics for the hand throttle, another electronic part that attached to the accumulator under the hood with two small vacuum style lines attached to it, both fuel filters 3- times along with removing the fuel tank and completely emptying it and starting over with fresh fuel. Please someone have the answers I desperately need.
Thanks in advance.
Darrel

Do you have a warning light and fault codes showing on the instrument cluster? Impossible to determine what is wrong on this forum without knowing what, if any, codes are showing. Not sure what accumulator you are referring to, but if it has two lines attached to a sensor, it sounds like the DPF pressure sensor. Did you have codes previously that led you to the hand throttle and sensor? Some models with an electronic foot throttle had problems with the foot throttle itself. Also, a bad crank sensor can cause the throttle to stop responding and show throttle fault codes. A bad ground can cause a multitude of weird problems. If it has the Shibaura engine, they were known for lots of regen problems which is why LS stopped using them. If it has done this since new, too bad it didn't get fixed while under warranty.
