A system and method for controlling an engine to limit engine output include determining engine speed, determining vehicle speed, determining a ratio based on the engine speed and the vehicle speed, comparing the ratio to a threshold, and controlling the engine to limit engine output based on the comparison. The ratio used for comparison may be selected from a plurality of ratios based on a current gear ratio which may be an actual or virtual (computed) gear ratio. The threshold may represent a low gear torque limit threshold in one embodiment. A vehicle speed sensor fault may also be considered to determine whether to limit the engine output. In one embodiment, engine output is limited by limiting engine torque.

[ What is claimed is:] [1.]1. A system for controlling an internal combustion engine to selectively limit engine torque, the system comprising:means for determining a gear ratio;means for comparing the determined gear ratio to a threshold value corresponding to a predetermined actual gear ratio and limiting engine torque when the determined gear ratio exceeds the threshold value.
