What does a throttle body do?

The throttle body acts as a valve between the air intake system and the engine's intake manifold. It controls the flow of air into the engine. When you press the accelerator pedal, the throttle body opens, allowing more air to enter, which in turn increases engine power. Inside the throttle body, there is a throttle plate that can rotate. When you press the accelerator, it opens to allow more air in. Releasing the accelerator causes the throttle plate to close, reducing the airflow.

The throttle body plays a crucial role in controlling the engine's idle speed. When the vehicle is at a standstill or moving at low speeds, the throttle plate may be partially closed to limit the amount of air entering the engine. This helps maintain a stable and efficient idle. By adjusting the position of the throttle plate, the engine control unit (ECU) can regulate the air-fuel mixture to optimize performance and fuel efficiency. When you need more power, the throttle plate opens wider to allow more air for combustion.

Safety Precautions:

Ensure the engine is cool.
