ABSTRACT:
An evaporative fuel-purging control system for an internal combustion engine incorporates a flowmeter arranged across a purging passage for outputting an output value indicative of the flow rate of a mixture of evaporative fuel and air being purged through the purging passage. Abnormality of the flowmeter is determined, based on a value of the output value therefrom assumed when the purging of the gaseous mixture is stopped. Alternatively or in combination, abnormality of the flowmeter is determined, based on a value of the output value therefrom assumed when the purging of the gaseous mixture is resumed after stoppage thereof.
