Abstract
A control system for an engine comprises a fault determination module and a remedial action control module. The fault determination module generates a fault signal after detecting an infrastructure fault. The remedial action control module directs a throttle valve of the engine to a default position after receiving the fault signal, determines when the throttle valve is moving to the default position, and directs engine shutdown when the throttle valve is not moving to the default position.
