Toyota will begin fixing accelerator pedals on recalled cars in America this week.
The sticking throttle problem, which has led to a recall of more than six million Toyotas worldwide, stems from a friction device in the pedal which is designed to provide "feel" by adding resistance and making the pedal steady and stable when depressed.
The device includes a shoe that rubs against an adjoining surface during normal pedal operation. The massive, worldwide recall has been sparked because, under specific conditions and over time, the system can begin to stick and release instead of operating smoothly.
The solution is to install a precision-cut steel reinforcement bar into the throttle assembly to reduce the surface tension between the friction shoe and the adjoining surface.
The parts to reinforce the pedals are already being shipped to the US for use by dealers, and Toyota says dealer training to fit the part is under way.
