APPARATUS FOR MANIFOLD AIR PRESSURE SENSOR FAILURE DIAGNOSIS ON VEHICLE AND METHOD THEREOF

摘要

A MAP (Manifold Air Pressure) sensor diagnostic method for a vehicle is provided which uses a calculated intake manifold air pressure as the intake manifold air pressure if the output signal of the MAP sensor is not within a predetermined range, or if the difference between the intake manifold air pressure indicated by the MAP sensor signal and the calculated intake manifold air pressure is not less than a predetermined value.
