The Toyota fly-by-wire throttle consists of the throttle pedal which contains the Throttle Pedal sensors, the ecm, and the throttle body which uses an electric motor to drive the throttle and a throttle position sensor to give feedback to the ecm to verify the throttle responded to the ecm's command. Don't have the schematics in front of me, but most systems use two sensors in the throttle pedal and both have to agree on position for a valid throttle input. A failure in either sensor results in a CEL and no throttle response.
