A limp-home control method for a hybrid vehicle may include: a fault determination step for determining, by a controller, whether a solenoid valve battery short circuit fault occurs in a transmission; a first limp-home step for controlling, by the controller, solenoid valves to implement a limp-home gear stage while maintaining a state where power is suppliable to the solenoid valves involved in shifting gears when it is determined that the solenoid valve battery short circuit fault exists; an engine necessity verification step for verifying, by the controller, whether engagement of an engine clutch is needed; and a second limp-home step for driving, by the controller, a solenoid valve controlling the engine clutch to engage the engine clutch, implementing limp-home driving by engine power when the engagement of the engine clutch is needed.
