What is a Throttle Body Service and Why is it Important


Bookmark and Share

Throttle body service is the throttle body cleaning and wiping of the bore and throttle blade. The service is important in order to keep the automobile running smoothly, efficiently, and safely.

What is it?

The throttle manages the flow of fluid and can increase or decrease the engine’s power. It does not control the power or the speed of the engine as is thought by many people. During a throttle body service, a technician cleans out or wipes the bore and throttle blade. When this is done and the air rate is checked and adjusted, a sensor does an idle that is computer controlled. If this is properly done, the car should operate in the idle mode as if it were new.

There is carbon and sludge that the PCV system deposits into the throttle body as the engine operates. This carbon and sludge is cleaned out during the throttle body service. How well the engine operates about a year after service is determined by the way the automobile starts, how well it idles when it’s cold or warm, and when accessories such air conditioning and heat are operating. The carbon and sludge will also affect the way the car starts from a total stop. A service such as this will keep the idle valve, which is computer controlled, clean. If it is left dirty and covered with carbon, it will have to be replaced and such a replacement can be costly.

An important part of the engine is the throttle body, which is part of the air intake system. The air intake system increases the amount of oxygen used for combustion with fuel. You can either gain or lose power with the air intake system depending on the vehicle’s ram. The throttle body is a part of this air intake system. Keeping the throttle body in good operating condition will keep the car running without costly occurrences.

Importance of the Throttle Body Service

Careful and regular throttle body service will keep the emissions from the engine’s exhaust system in check. There is also increased sound when the throttle is applied by way of the accelerator. If the vehicle is operated at lower speeds, there is less noise coming from the engine. However, at higher speeds, the engine tends to become very noisy. These two statements make the throttle body service important in itself, as it makes the automobile more environmentally friendly. A complete throttle body service is recommended every 15,000, 40,000, and 75,000 miles to be sure that the automobile is functioning properly.

It is most important to have the throttle body serviced regularly to avoid the high cost of replacement. The cost of throttle body service or replacing the throttle body varies with the year, make, and model of the car. But, no matter what that year, model, or make may be, replacement is not inexpensive. Excluding the cost of replacing the throttle body for the moment, what is perhaps even more important, is to have the throttle body serviced regularly to keep your car running smoothly and efficiently.
