Original Abstract Submitted
a controller for an internal combustion engine is provided. a control circuit performs active control for an air-fuel ratio of exhaust gas. during execution of the active control, an increasing process for increasing an intake air amount is executed. during execution of the active control, a cumulated intake air amount is calculated. a sensor detects the air-fuel ratio. it is determined whether an anomaly has occurred in the sensor during execution of the active control. a maximum execution period of a sensor diagnostic process is set to a period for the cumulated intake air amount to reach a specified threshold value. the increasing process is prohibited during the execution of the sensor diagnostic process.
