A system which monitors the performance of at least one HC sensor arranged in an exhaust passage of and internal combustion engine. According to a first aspect of the invention, a value of output from the at least one HC sensor is stored, which is assumed when the fuel supply to the engine is cut off, and a value of output from the at least one HC sensor is corrected by the stored value.
