Bulldozer Case 1150K motor problem problem

Stamped friends, I hope you can help me with the problem I have with the Bulldozer Case 1150 K, the yellow alarm remains on the board and when you press the diagnostic buttons it tells me that it refers to a motor failure. The concessionaire of my country proceeded to review the tractor computer but has not given any results and the tractor is found working with this fault, and the alarm cirena has been deconed to not bother the operator. The question is whether any problem is fault or if the engine has the same problem, which I do not believe because it normally works and the maintenance are strict, if it is a sensor, please tell me where it is having had the same one that causes the problem
