What are the symptoms of a faulty throttle body?

The throttle body is one of the most important mechanical parts to ensure the optimum mixture of air and fuel in your engine. Located after the flow meter and air filter, it works in conjunction with the injectors that regulate the flow of fuel. Through the valve, the throttle body regulates the amount of air entering the engine.

🔎 What causes HS throttle valve symptoms?

The throttle body may show signs of wear and be severely impaired. However, it is important to understand the causes of these symptoms, which may be:

• The throttle body is dirty : impurities have accumulated in it, and it can no longer perform its functions correctly;
• Flow meter sensor clogged : The air is not filtered properly and this will clog the meter as well as the throttle body.

Thus, these two situations will cause unusual signs of using your vehicle. Thus, you will be in the presence of the following events:

1. Ignition engine warning light : since the engine no longer works properly, it will pollute the environment more and trigger a warning with the engine warning light to inform the driver;
2. Excessive fuel consumption : since the amount of air is no longer optimal for good combustion, there will be compensation at the level of the injected fuel dose;
3. Vehicle instability : Since the throttle body valve does not open properly for air intake, this can cause phase imbalance in your vehicle with engine jerks.
4. The engine will stall : because combustion does not work properly, the engine may have difficulty starting or even stall during your travels in the car;
5. Loss of engine power : The motor will no longer be able to provide the same power, especially during the acceleration phases.

💡 What are the solutions for HS Throttle Body Malfunction Symptoms?

The throttle body is a wear part that requires special maintenance if you want to extend its life. If it is already faulty, you can choose from several different solutions:

• Clean the throttle body : Depending on the model you have, you can clean it yourself with a penetrating oil spray;
• Run descaling on a professional : This procedure removes all dirt, impurities and soot deposited in your car's engine system as well as in the exhaust pipe.

🛠️ How to change the throttle valve of your car?

If the throttle body is completely out of order and cleaning is not enough, you can replace it yourself. Follow our step by step guide to complete this maneuver easily.

Required material:

• Toolbox
• Protective gloves
• New throttle body

Step 1: disconnect the battery

The throttle body is often found underneath a car battery. Therefore, you need to disable it in order to access it. In some cases, it is necessary to remove the air filter as well.

Step 2: Remove the worn out throttle body.

First you will need to unscrew the fastening screws and disconnect the connector from the box. Then you can gently lift it out of the case.

Step 3: Install the new throttle body

Using the mounting screws and connector, you can install a new throttle body. Then you will need to assemble your car's air filter and battery. Do not hesitate to check your car afterwards by starting it.

⚠️ What are other possible symptoms of a malfunctioning throttle body?

The throttle body, when it stops working properly, will start calling wear of other parts necessary for the proper functioning of the engine... In particular, it can clog the catalytic converter, particulate filter or injectors. In addition, the exhaust gas recirculation valve can also be damaged and become dirty over time, as well as when using a vehicle with a faulty housing.

This is why it is highly recommended to intervene immediately if one of the engine parts is damaged, otherwise it will lead to premature wear of other parts.

The throttle body is one of the most important parts of the engine, ensuring proper mixing of air and fuel in the latter's combustion chambers. It is very important to maintain the engine correctly on a regular basis in order to prevent its breakdown. Engine contamination is one of the first causes of failure of one of the components necessary for its proper functioning.
