What Is a Car Throttle Body?
The throttle body is an essential component of a car’s engine. It is responsible for controlling the amount of air that enters the engine, which in turn affects the engine’s power output. The throttle body is typically located between the air filter and the intake manifold.
How Does a Throttle Body Work?
The throttle body is a butterfly valve that is controlled by the accelerator pedal. When you press down on 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.
The amount of air that enters the engine is measured by the mass air flow (MAF) sensor. The MAF sensor sends a signal to the engine’s computer, which then adjusts the fuel mixture to match the amount of air that is entering the engine.
What Are the Symptoms of a Bad Throttle Body?
A bad throttle body can cause a variety of symptoms, including:
- Engine idling rough or stalling
- Engine hesitation or stumbling
- Reduced engine power
- Increased fuel consumption
- Check engine light
