Abstract
A throttle position sensor is provided for detecting opening degree of the throttle valve at regular intervals to produce an opening degree signal dependent on the detected opening degree. A memory has a stored opening degree signal. A detected opening degree signal detected by the sensor is compared with an opening degree signal stored in the memory. The stored opening degree signal is rewritten with the detected opening degree signal when the latter is larger than the former. Thus, a signal representing a maximum opening degree is stored in the memory.
