Abstract
An ECU executes a program including a step (S) of limiting the maximum opening amount of a throttle valve to TH () when failure has occurred in a pressure sensor ('YES' in step S); a step (S) of limiting the maximum opening amount to TH () when open failure has occurred in at least one of two vacuum pressure ASVs provided for banks of a V-type engine, and an electromagnetic ASV ('YES' in step S); a step (S) of limiting the maximum opening amount to TH () when open failure has occurred in both of the vacuum pressure ASVs (“YES” in step S); a step (S) of limiting the maximum opening amount to TH () when open failure has occurred in one of the vacuum pressure ASVs (“YES” in step S); and a step (S) of reducing the throttle valve opening amount TH to the limited maximum opening amount.
