Car Throttle Body: The Complete Guide
The throttle body is a critical component of your car’s engine. It controls the amount of air that flows into the engine, which in turn affects the engine’s power and efficiency. A faulty throttle body can cause a variety of problems, including engine stalling, poor acceleration, and decreased fuel economy.
How the Throttle Body Works
The throttle body is located between the air filter and the intake manifold. It consists of a butterfly valve that is controlled by a cable or electronic actuator. When you press the gas pedal, the throttle valve opens, allowing more air to flow into the engine. When you release the gas pedal, the throttle valve closes, reducing the amount of air that flows into the engine.
The throttle body is also responsible for controlling the idle speed of the engine. When the engine is idling, the throttle valve is slightly open, allowing a small amount of air to flow into the engine. This keeps the engine running at a constant speed.
Symptoms of a Faulty Throttle Body
A faulty throttle body can cause a variety of problems, including:
- Engine stalling
- Poor acceleration
- Decreased fuel economy
- Rough idling
- Check engine light
Causes of a Faulty Throttle Body
A faulty throttle body can be caused by a variety of factors, including:
- Carbon buildup
