ABSTRACT:
An ECU (electronic control unit) determines whether a turbo charger is defective or not based on degree of deviation between a target boost pressure Pimtrg and an actual boost pressure Pim of the turbo charger. Further, ECU estimates exhaust gas pressure of an exhaust passage from the internal combustion engine to the turbo charger based on a state of engine operation, and determines whether or not the estimated exhaust gas pressure is relatively low. When it is determined that the exhaust gas pressure is relatively low, the manner of defect determination is changed such that the determination of defect is not readily made.
