What is a throttle body?

A throttle body is an important component in the air intake system of a vehicle. It controls the amount of air that enters the engine, which is essential for fuel combustion and engine performance.

The throttle body is typically located between the intake manifold and the air intake filter. It consists of a valve that opens and closes to control the airflow, along with sensors that monitor the position of the valve and send signals to the engine control unit (ECU).

Throttle bodies can be either mechanical or electronic. Mechanical throttle bodies are controlled by a cable or linkage connected to the gas pedal, while electronic throttle bodies utilize sensors and an electric motor to control the valve position.

In modern vehicles, electronic throttle bodies have become more common due to their ability to provide precise control over the engine's air/fuel mixture and improve fuel efficiency.

Regular maintenance of the throttle body, such as cleaning and inspecting for any signs of wear or damage, is important to ensure proper engine performance and fuel efficiency.
