Why is the engine indicator light flashing?

[DelilahLynn]

Engine indicator light flashing is caused by the oxygen sensor detecting an abnormal air-to-fuel ratio. If the short-term fuel trim correction coefficient is found to be too large or too small for a period of time, the long-term fuel trim correction coefficient will be increased or decreased accordingly. This indicates that the engine control unit has been adjusting the engine operation with either enriched or leaner air-fuel mixture over a period of time. An engine is a machine that converts other forms of energy into mechanical energy, including internal combustion engines (such as gasoline engines), external combustion engines (such as Stirling engines, steam engines), and electric motors. The term engine can refer to either the power generation device or the entire machine including the power unit.
