element is attached to the motor to feed back its position so the controller can constantly track the position of
the motor with respect to the gas pedal.
As it is shifted, a motor arrangement in the transmission changes the gears as required, eliminating the direct
cable connection. These new systems are highly reliable and the weight reduction and ease of assembly provide
substantial cost reduction for the end consumer.

tank. The pivot arm is attached to a mechanism that moves a wiper contact
across the resistor surface, translating the float position into an electrical
signal that causes the meter on the dashboard to indicate fuel capacity.
