What Symptoms Indicate a Clogged Throttle Body?
Several symptoms indicate that the throttle body should be cleaned. Explain what the throttle body is and why it is dirty before starting the symptoms.
Have you ever wondered what happens when you step on the gas? Let's explain in simple words. A mechanical cable or a sensor and actuator connects the throttle body to the accelerator pedal. The throttle body moves in response to the movement of the accelerator pedal. Controls the amount of air entering the engine.
The computer calculates the amount of fuel to inject based on the amount of air. The throttle body controls the amount of air entering the engine. During combustion in the combustion chambers, excess carbon residues and dirt accumulate on the throttle body. This leads to problems that we will discuss later. Here are 3 signs of a dirty body throttle:
- Stalling - The ECU (Engine Control Unit) determines the amount of fuel to be injected into the combustion chamber based on the amount of air entering the combustion chamber through the throttle body. As a result, if the throttle body is dirty or clogged, the required amount of air is not injected, causing the engine to stall.
- Unstable idle: to ensure smooth idle operation, the "idle control" sensor mounted on the throttle body is used. The purpose of this sensor is to draw a specific amount of air into the engine during idling to ensure smooth operation. This sensor will not work properly if the throttle body is clogged or blocked by dirt, and the car will not freeze at idle.
- Erratic Performance - Misfires caused by a faulty or dirty throttle body can cause erratic performance due to insufficient air/fuel mixture.
How to Clean a Throttle Body Without Disassembling It
The throttle body should be cleaned regularly. According to most manufacturers, the throttle body should be cleaned every 15,000 miles.
If you are still unsure and unsure about doing this job yourself, the next time you have your car serviced in Reading, consult a trained mechanic.
Cleaning the Throttle Body Without Removing It: Step-by-Step Instructions
The first step in learning how to clean your throttle body without removing it is to prepare your workspace. Because the substances you are working with are flammable, you should do so outdoors in a well-ventilated area. Having decided on the proper location, the throttle body should be located under the hood in the engine compartment. Here are some tips to help you find it quickly:
- Between the air filter and the intake manifold is the throttle body.
- Aluminum is used in the manufacture of the throttle body.
- The throttle body is attached to the accelerator pedal via a metal cable on some older models, making it easy to identify by pressing the accelerator pedal while the engine is off and looking at the moving part.
When locating the throttle body, proceed with caution. This is because it is connected to tubes, hoses, and in some cases electrical connections. Some of these parts should be avoided because if something goes wrong, it will be difficult to restore them to their original state. When in doubt, find a full auto service near me and let the professionals take care of it.
Tools and materials required
Before you begin this project, you must collect the necessary tools and materials, which include:
- This screwdriver set includes Torx screwdrivers.
- For stubborn stains and dirt, use a soft toothbrush.
- Work in a light-hearted manner.
- To remove the clamps, use pliers.
- Safety goggles and rubber gloves
- Throttle body cleaner- The most important section of this guide. Use caution when using this cleaner to avoid damaging the internal parts and sensors connected to the throttle body. Because it is effective and safe to use in conjunction with the throttle body, we recommend WD-40 Specialist Carb/Throttle Cleaner.
- A paper towel is used to clean up dirt and stains.
Now you can prepare the vehicle and equipment and begin the cleaning process with the right tools and materials.
To avoid a short circuit, first, disconnect the negative terminal of the vehicle battery.
The next step is to locate the large air duct that connects the throttle body and the air filter. It is usually held in place with a metal clamp. Loosen the screw with the screwdriver and carefully remove the air duct. Please take your time with this. Unplug all electrical cables connected to the air duct.
The third step is to remove the air ducts or hoses that block the view of the movable plate inside the throttle body. Be careful not to damage any of the internal gaskets.
The fourth step is to put on your protective gear, which should include rubber gloves and safety glasses. Start by spraying throttle body cleaner on the inside of the throttle body and removing the sticky dirt from the brush.
The fifth step is to go back and repeat the previous steps several times. After each use, wipe off any dirt with paper towels. Repeat the process until the bare metal is clean. Carefully remove the passive sensor, clean it and dry it completely.
The sixth step is to wipe the throttle body with a paper towel to keep it dry. Make sure there is no liquid left in the throttle body.
The seventh step is to replace the air ducts and tighten the clamps with a screwdriver or Torx screwdriver.
After reinstalling the airlines and any electrical connections you may have removed, the eighth step is to retrieve your tools and materials from the engine compartment and reconnect the negative battery terminal. Now you can start to start the engine.
The ninth step is that after cleaning the throttle body it is normal to have problems starting the engine, stumbling, or having unstable rpm. This is due to burning throttle cleaner residue in the intake manifold. After it shuts down, everything will go back to normal.
Step ten is taking your car for a test drive to see if cleaning the throttle body makes a difference. You will notice the difference in the performance of the engine, the presentation of fuel-saving items, and the sound. This is the same technique used to clean the electronic throttle body.
