What is a throttle body?
The throttle body is an air metering device, or an internal combustion engine, that keeps air and fuel flowing within your vehicle’s cylinders.
Placed between the intake manifold and the air filter, the throttle body uses a butterfly valve to let in the correct amount of air to the engine. This prepares the mixture of fuel and air that your engine will combust to produce energy.
When should I replace the throttle body on my car?
Here are a few common symptoms that your throttle body may be failing:
The check engine light is on
Your idle speed is too high or too low
The transmission is shifting poorly
While it’s not technically unsafe to drive with a dysfunctional throttle body, you probably won’t get much use out of your vehicle. The car will likely have limited power and noticeably lack in engine performance.
How often do you need to replace a throttle body?
While there’s no exact timeline or set mileage when it comes to the lifespan of your throttle body, you should consider replacing it every 100,000 to 150,000 miles.
This is a wear-and-tear part. With time and regular use, throttle bodies get dirty from oil residue and carbon buildup. To prevent throttle body problems, make sure to clean your throttle body approximately every 75,000 miles.
Is replacing a throttle body yourself easy?
Unless you’re experienced in mechanical DIY projects and auto repair, replacing a throttle body isn’t an easy job. It requires technical knowledge and access to various tools, including screwdrivers, a socket set, and needle nose pliers.
For the average driver, it’s a good idea to let a professional mechanic handle this replacement.
