A throttle body is a component in the air intake system of an internal combustion engine that regulates the airflow entering the engine. It contains a throttle plate, which can be opened or closed by the driver or the engine control module to control the engine’s air intake and, subsequently, the fuel-air mixture. The throttle body plays a crucial role in determining the engine’s power output and overall performance. Modern vehicles often use electronic throttle bodies (ETBs) that are controlled by the engine’s electronic control unit (ECU) for more precise and efficient throttle operation. Issues with the throttle body can lead to poor acceleration, idling problems, and reduced fuel efficiency. Regular maintenance and periodic cleaning are essential to ensure optimal throttle body performance.
