Abstract
A control device for the internal combustion engine includes a pulsation detector, a path length calculator, and an anomaly detector. The pulsation detector detects the pulsation of the intake air flowing through the intake passage based on output signals from the air flowmeter. The path length calculator calculates the path length, which is a parameter that is correlated with the degree of the pulsation, based on the pulsation of the intake air detected by the pulsation detector. The anomaly detector determines that the fresh air passage is detached if the path length calculated by the path length calculator is less than or equal to a determination value and detects an anomaly in the fresh air passage.
