Where was the accelerator of Buick Excelle in 2005?

In 2005, the throttle position of Buick Excelle was behind the air filter element of the air intake system.

Throttle is the throat of the engine, which can control the intake of the engine. When the driver steps on the accelerator pedal, the fuel injection quantity is not directly controlled, but the throttle opening is controlled. When the throttle opening becomes larger, the sensor detects that the amount of air entering the engine increases.
