I am trying to find out how many cars use an electrical control for the accellerator (or throttle) instead of a cable control.
I understand the bits involved are a potentiometer (variable resistor) on the accellerator pedal, which then sends an electrical signal to a similar device at the fuel supply end, to adjust the amount of fuel issued to the cylinders to control the vehicle speed.
I believe it is only something used on more modern vehicles, but would be interested to know what percentage of newer vehicles use this method.
