1. A method for controlling an operating state of an internal combustion engine having an intake air passage with a throttle valve, comprising:

  • detection step for detecting a pressure in the intake air passage of the engine downstream of the throttle valve and producing a pressure signal;

    calculation step for calculating a difference between a latest sampled value of said pressure signal and a preceding sampled value of said pressure signal, and adding a value corresponding to said difference to said latest sampled value to produce a corrected pressure value; and

    controlling step for controlling an amount of fuel to be supplied to the engine on the basis of said corrected pressure value, wherein said corrected pressure value is made equal to a predetermined value when said corrected pressure value becomes greater than said predetermined value.
