A control apparatus for an engine, the control apparatus includes an ECU. The ECU is configured to: (i) estimate a characteristic value indicating divergence from a reference value of an intake air volume, (ii) store the characteristic value as a learnt value, (iii) calculate the characteristic values for an opening degrees for which learning has not been completed, (iv) learn the characteristics of the throttle valve and reflect the characteristics in control of the intake air volume, (v) update the learnt value at which an engine rotation speed is equal to or greater than an idling rotation speed during an initial engine operation after initialization of the learnt values, (vi) update the learnt value at which an engine rotation speed is lower than an idling rotation speed, by storing a value equal to the learnt value for the smallest opening degree for which learning has already been completed. |
