Have you been told that it’s time to replace your throttle body? Before we get into some specifics on repairs and replacements, let’s take a moment to talk about what it is, and what it does in your vehicle.

The throttle body is a part that is attached to the air intake system, which is attached to the  vehicle’s engine. A throttle body’s function is to control the amounts of air that is flowing into the engine, based on how hard a driver is pushing down the driver accelerator pedal.

In order for this part – and your car – to run smoothly, the engine needs to have a good mixture of air and fuel. And if your throttle body isn’t providing enough, or too much air in the engine, that can cause major vehicle problems.

If the ‘check engine’ light has recently turned on in your vehicle, then it could be the throttle body that’s causing the problem. For an automotive technician to get to the root of the problem, diagnostic tests will need to be performed, which will help to identify if it’s the throttle body that’s failing on the engine.

Once the problem is identified, then a new throttle body will need to be installed on the air intake system to fix the problem. While some automotive repair shops will allow you to bring in a throttle body you’ve purchased at another retailer, HomeTowne does not install outside parts on cars. Not only does this ensure that the right throttle body is being installed on your car, but it also allows our shop to give you a full two year, 24,000 mile nationwide warranty on the part.

So if your engine light is on, or you know your throttle body needs to be replaced, make sure you’ve got an experienced shop working on it right away.
