ABSTRACT:
If an inlet pressure of a supply pump sensed by an inlet pressure sensor is higher than a high-pressure side threshold value and an integrated period of the state exceeds a predetermined integration period, it is determined that a high pressure abnormality occurs, and processing for the high pressure abnormality is performed. Thus, failures of the supply pump due to the high pressure abnormality can be avoided. If the inlet pressure of the supply pump is lower than a low-pressure side threshold value and an integrated period of the state exceeds a predetermined integration period, it is determined that a low pressure abnormality occurs, and processing for the low pressure abnormality is performed. Thus, failures of the supply pump due to the low pressure abnormality can be avoided.
