A malfunction detection apparatus is disclosed for a forced induction system. The system includes a compressor provided on an upstream side of a throttle valve in an intake passage of an engine, an upstream intake pressure sensor that detects intake pressure between the compressor and the throttle valve, and an atmospheric pressure sensor that detects atmospheric pressure. The malfunction detection apparatus includes a malfunction detection program that makes a comparison between the atmospheric pressure detected by the atmospheric pressure sensor and the upstream intake pressure detected by the upstream intake pressure sensor. The comparison is made in an operating state of the forced induction system in which the compressor compresses an amount of air that is approximately equal to or less than a predetermined amount to thereby determine whether the upstream pressure sensor has a malfunction.
