How much does a throttle body service cost?
The throttle body service involves cleaning the throttle body with a special cleaning solution and removing carbon deposits from the throttle valve. In some cars, the idle speed must be re-learned after the service was done. The throttle body service is not very expensive, ranging from $60 to $180 depending on the complexity.
What should I do if my throttle body is bad?
As a part of your regular service intervals, include the air induction service and fuel injection flush to clean out any carbon deposits and dirt. You will need to have the check engine light shut off by a qualified mechanic.
Why is the throttle body important in a car?
In modern fuel injected cars, the throttle body is an essential part of the air intake system, controlling the flow of air into the engine, which is used to effectively combust fuel in the pistons. Getting the right amount of air is vital. Too much air or too little air can make your engine run lean.
What causes dirt on inside of throttle body?
Dirt, grime, and carbon deposits on the inside of the housing. Similar to dirt and grime, carbon deposits can create an uneven surface inside the walls of the throttle body which can disrupt the atomization of the air/fuel mixture.

What is the function of the throttle body?
The throttle valve controls engine RPMs by regulating the air flow. A small electric motor inside the throttle body opens and closes the throttle valve. Besides responding to the gas pedal, the throttle body has one more important function: in most cars, it maintains the engine idle speed.

How does a GM throttle body relearn procedure?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position.
What’s the best way to clean a throttle body?
Any access oil that drips out can be re-cleaned by spray some of the throttle body cleaner onto the rag and wiping it away. Do not spray it directly into the throttle body as this can wash away the oil we just applied. Make sure the throttle plate is working correctly, then reinstall all products in reverse of installation.

Let the cleaner soak in for a minute or two. Spray throttle body cleaner on a clean shop rag and clean the inside of the throttle body. Start by cleaning the inner housing and wipe the rag along the entire surface. Open the throttle blades with the throttle control.
How does the throttle body work on a Ford?
The pedal simply provides an electronic signal, telling the throttle body how much acceleration you’re requesting. A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request.
What happens if you have a dirty throttle body?
A dirty throttle body typically restricts the flow of air and fuel into the engine. This can result in symptoms that can impact the overall operation of your vehicle. Some of the more common warning signs that you have a dirty throttle body that requires cleaning may include the following:
Can a bad throttle body cause strange fuel mixture?
If your car feels like it lost half of its power when accelerating, it can absolutely be caused by a bad throttle body. You already know that a bad throttle body will cause a strange fuel mixture.
What should I do after replacing my throttle body?
After replacing the throttle body to your engine, if the engine light was on and has a pending code, the code will go away. If the code was a hard permanent code, then the ECM (computer) would need a hard reset. Remove the negative battery cable (-) and keep it off for about 13 minutes, then hook up the battery cable and make sure it is tight.
Is the throttle body dependent on other parts?
This is carried out electronically in electronic fuel injection engine systems. In most vehicles, there is only one throttle body, with a rare exception of special, larger vehicles. The function of the throttle body is also dependent on other parts, such as the air filter.
When do you know you have a bad throttle body?
If you notice that your car has a very uneven acceleration – sometimes it is fast and sometimes slow, you might have a bad throttle body. Misfires occur either when the air-fuel mixture is very wrong or when it comes to a weak spark from the spark plug.
What do you need to know about a throttle position sensor?
What Is a Throttle Position Sensor? This vital sensor allows your engine to maintain a proper amount of air. This feature is dependent on the throttle valve. When you press down on the gas pedal, your throttle body unit’s valve opens.

Can a bad throttle body cause high RPM idle?
High RPM Idle The throttle body controls the engine’s idle to make sure it is always holding a steady RPM. If there is a problem with the throttle body, it may cause the be way too high. A not calibrated throttle body can also cause this.
If your car feels like it lost half of its power when accelerating, it can absolutely be caused by a bad throttle body. You already know that a bad throttle body will cause a strange fuel mixture.
Where is the throttle cable on a car?
Step 1: Locate the throttle cable. One end of the throttle cable is located in the engine compartment, attached to the throttle body. The other end is on the driver’s side floor, attached to the accelerator pedal.
Which is the best throttle body cleaner to buy?
The popular CRC throttle body cleaner is my favorite and one of the most popular cleaners with professional mechanics. It quickly cleans the most gummed up throttle bodies to restore lost performance and possibly increase your gas mileage. Your engine will feel like new again and best of all is the price.
What makes a throttle body a performance throttle body?
Performance throttle bodies are built with airflow tubes that are larger in diameter than OEM ones. Naturally, this increases airflow. Throttle bodies are given an airflow rating based on the number of cubic feet of air that can pass through in one minute (“CFM” for short). Use this rating as a gauge when making your selection.
When does a throttle body need to be serviced?
There is no specific mileage requirements and some cars may never need this service. A throttle body usually gets dirty at higher mileage (after 60K-80K miles), mostly in cars that are often driven in stop-and-go city traffic or when oil changes are not done…
Is the throttle body replacement covered under powertrain?
The car threw a TPS code, and they told me the throttle body needed replacing, because it’s sticking. Cool, makes sense, go for it. Now, they tell me that it is NOT covered under the 100k powertrain warranty. I worked as a tech at a (non-GM) dealership for years before I went to law school.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
How much does it cost to replace a throttle body?
Fix that, and all the other codes go away, and if that doesn’t work the whole throttle body will need to be replaced because the sensors and solenoids are encased in plastic. This particular throttle body cost about $300.00.
What happens when you clean the throttle body?
When you manually clean the throttle body, you’ll be cleaning the blades themselves. This can cause the electronic throttle body not to operate correctly. It is recommended you remove the throttle body from the vehicle and clean it or have a professional mechanic complete this service for you.
How did fuel injection change the throttle body?
Fuel injection systems have since then grown into finely tuned, electronically controlled and operated machines that have improved engine fuel burning efficiency by as much as 70% over the past three decades. The throttle body hasn’t changed much in mechanical design or in function since the early mechanical fuel injection systems were in use.
Where is the throttle body on a car?
In most cars, it’s not very difficult. The throttle body is installed at the intake manifold and to check its condition your mechanic may have to remove the intake boot. Is it possible to clean the throttle body as a DIY project? Some manufacturers require a very specific procedure to clean the throttle body.
