More Information
Summary:An engine-controlling atmospheric pressure detection system which is capable of detecting atmospheric pressure highly frequently, even during descending, based on a signal from a pressure sensor for detecting air-intake pressure. An actual air-intake pressure is normalized in relation to air-intake pressures at high and low altitudes, respectively, when a throttle valve is closed, which pressures have been stored in a ROM, thereby determining the resultant value as a parameter. The atmospheric pressure is thus detected from the minimum value of such a parameter.
