摘要： A method of monitoring air flow restriction in an air intake of an internal combustion engine includes monitoring a plurality of manifold absolute pressure (MAP) samples and determining respective MAP thresholds corresponding to each of the MAP samples. Each of the MAP samples is compared to its respective MAP threshold. A percentage of failed MAP samples is determined based on the comparing and an over-restricted air intake condition is selectively indicated based on the percentage of failed MAP samples.
