Abstract
A hybrid vehicle may include an engine controller that determines an activation state of an oxygen sensor when the engine controller is requested to operate an engine and controls a voltage applied to the oxygen sensor depending on whether or not the oxygen sensor is in an activated state, and a vehicle controller that controls a voltage of a battery of the hybrid vehicle and applies the voltage of the battery to the engine controller. The engine controller outputs an activation demand signal for the oxygen sensor to be activated to the vehicle controller when it is determined that the oxygen sensor is not in the activated state.
