A materials handling vehicle includes a mast, a load handling structure supported on the mast, one or more operator controls, and a lifting structure having a chain structure for performing a lifting and lowering of the load handling structure. The materials handling vehicle further includes a height sensor for generating a height signal corresponding to vertical movement of the load handling structure relative to the mast, and a vehicle control module for processing the height signal received from the height sensor and an operator control signal received from the one or more operator controls. The vehicle control module evaluates the height signal and the operator control signal and disables one or more vehicle functions if the height signal does not correspond to the operator control signal.
