Abstract

A system for a vehicle includes an active fuel management (AFM) module, an expected engine speed determination module, and a disabling module. The AFM module selectively cuts off fuel to at least one cylinder of an engine and maintains valves of the at least one cylinder in closed positions. The expected engine speed determination module determines an expected engine speed based on a position of a shift lever of a manual transmission measured using a position sensor module. The disabling module selectively disables the AFM module based on the expected engine speed.
