Abstract
A method for controlling engine torque in a vehicle during a default throttle condition includes determining whether a throttle of the engine is in a default throttle condition, determining whether the engine is producing more torque than desired if the throttle of the engine is in the default throttle condition, and applying an accessory load to the engine if the engine is producing more torque than desired in the default throttle condition.
