摘要： PROBLEM TO BE SOLVED: To correctly judge an abnormal state in which correct operation is not possible due to operation failure even in a period when an engine operates in a steady state for a long time. SOLUTION: An electric instruction (is) for monitoring abnormality is output for an EPC valve and, as a result, a detection value S of a sensor obtained when the electric instruction (is) for abnormality monitoring is output for the EPC valve is compared with the electric instruction (is) for monitoring abnormality. In the case in which a level of the detection value S of the sensor is appropriate for a level of a signal of the electric instruction (is) for abnormality monitoring, it is judged that a hydraulic servo valve operates normally. The detection value S of the sensor obtained when the electric instruction (is) for abnormality monitoring is output for the EPC valve is compared with the electric instruction (is) for abnormality monitoring and the level of the detection value S of the sensor is inappropriate for the level of the signal of the electric instruction (is) for abnormality monitoring, it is judged that the hydraulic servo valve operates abnormally.
