What is the function of throttle body on 2005 ford freestyle?

The throttle body on a 2005 Ford Freestyle, like on any other vehicle, controls the amount of air that flows into the engine. It's essentially a valve that regulates airflow based on the driver's accelerator pedal input.

When you press the accelerator, the throttle plate inside the throttle body opens, allowing more air to enter the engine. This increased airflow, combined with a corresponding increase in fuel injection, leads to a higher engine speed and power output. When you release the accelerator, the throttle plate closes, reducing airflow and engine speed.

In short, the throttle body is a crucial component in controlling the engine's power and speed in response to driver input.
