What Does the Throttle Body Do in a Car?
The throttle body is a component of a car’s engine that regulates the amount of air that enters the engine. It is located between the air filter and the intake manifold. The throttle body is controlled by the accelerator pedal. When you press the accelerator pedal, the throttle body opens, allowing more air to enter the engine. When you release the accelerator pedal, the throttle body closes, reducing the amount of air that enters the engine.
How Does the Throttle Body Work?
The throttle body is a butterfly valve that is controlled by the engine’s computer. The computer opens and closes the throttle body to control the amount of air that enters the engine. The computer uses a variety of sensors to determine how much air the engine needs. These sensors include the mass air flow sensor, the throttle position sensor, and the oxygen sensor.
What are the Symptoms of a Bad Throttle Body?
A bad throttle body can cause a variety of problems, including:
- Stalling
- Hesitation
- Rough idle
- Reduced power
- Increased fuel consumption
