Abstract
Disclosed is an inactive-state determining method of an oxygen sensor, including the steps of determining whether the oxygen sensor is in a condition where the oxygen sensor can be activated. It is determined whether an engine is in an idle state. A predetermined time is counted. It is determined whether electromotive force from the oxygen sensor is below a slice level even after the predetermined time is passed. An amount of fuel injected is increased by 20%. It is determined whether the electromotive force of the oxygen sensor is below the slice level even when the increased fuel is injected.
