How do you reset the Throttle Position Sensor on a Ford Fusion?

To reset the Throttle Position Sensor (TPS) on a Ford Fusion, first, ensure the vehicle is off. Then, turn the ignition to the "On" position without starting the engine, and wait for about 10 seconds. Next, press the accelerator pedal to the floor and hold it for about 10 seconds, then release it. Finally, turn the ignition off and start the engine; this should reset the TPS.
