Abstract
A vehicle electronic throttle control assembly includes a position controlling device that automatically returns the throttle assembly components to a home position. A generally arcuate spring interacts with a plate portion supported on a shaft that is associated with the throttle blade portion. The natural bias of the spring biases the shaft and blade portion into a home position. The position controlling device accommodates situations where the electric motor assembly of the throttle control arrangement fails to operate as desired or does not receive proper power or command signals, for example.
