Abstract
An engine controller is provided. A second calculation process calculates an intake air amount without using an output of an air flow meter. A second determination process determines whether an intake air pulsation in an intake passage is great without using the output of the air flow meter. When the intake air pulsation is determined to be great by at least one of a first determination process and the second determination process, a calculation method switching process selects the calculated value of the intake air amount obtained by the second calculation process as a calculated value of the intake air amount used to determine an operation amount of an actuator.
