Abstract
An engine control apparatus includes a stack detecting unit, a count processing unit, a stack value storage control unit, and an abnormality determination unit. The abnormality determination unit determines that a sensor has a stack abnormality when a count value by the count processing unit becomes equal to or more than an abnormality determination threshold. When maximum value of the detected value of the sensor detected during a determination period is lower than a value stored in a storage unit and a stack state has not been detected by the stack detecting unit during the determination period, the count processing unit does not count up a counter and does not reset the counter.
