Cars manufactured today usually require an adequate throttle body cleaning to provide air/fuel mixture to fuel injection cylinders. It is part of the air intake system, and it determines how much air can get into the combustion chamber. Normally, the throttle body has a housing unit with a throttle plate that revolves around a shaft. Check out this cleaning guide for the throttle body. It will help you learn how to keep the throttle body in optimal conditions at all times.

What is the Throttle Body?

The throttle body is basically the carburetor, and it determines just how much air/fuel mixture gets into the manifold. When the throttle body releases the air-fuel mixture into the manifold, the fuel injection nozzles eject into the different cylinders.

The throttle body has always been an integral part of the fuel injection system. It helps to efficiently control the speed of the car by controlling the speed of the engine. When a motorist pushes down the accelerator, the throttle plate will open, and the air gets into the engine.

When released, the plate closes back up, cutting off the airflow supply into the combustion chamber. If you properly clean your throttle body, it keeps the engine running; and when your throttle body is in stellar condition, it offers more horsepower to your vehicle.

How Does it Work?

The throttle body occupies the space between the intake manifold and the air filter; it features a throttle system and effectively controls an important part of spark ignition, which is the airflow. Airflow is a part of the atomization procedure. It assists in the regulation of the air-fuel mixture ratio needed to spark the engine.

What really regulates the throttle body is the temperature sensor; it also determines the temperature of the mixture, making its way into the fuel injections system. When the throttle body regulates the temperature, it sparks the ignition in the vehicle and promotes fuel efficiency.

The throttle plate, which you can also call the butterfly valve, controls airflow. The accelerator regulates the accelerator, and when the driver presses down on the gas pedal, the butterfly valve opens up. This allows air into the combustion chamber, which then makes the vehicle gain more speed.

Symptoms of Failing Throttle Body

When there are grimes and other dirt covering up the throttle body, it affects the air-fuel flow into the engine; this can affect your engine negatively. A sign of a failing throttle body is when the vehicle has a problem shifting into higher gears.

A dirty fuel injection system affects gear shifting in a vehicle. When the throttle body gets all dirty, it reduces the RPM band of the engine. The consequence is that it makes the engine to delay when it should be shifting.

Another clear sign is when the engine idling is rough; the excess carbon buildup in the throttle blades affects how the engine works. The only way to effectively get rid of this build-up is to clean up the throttle body.

Also, the engine will stumble during acceleration if there’s a clogged throttle body. This is because of the negative impact of grime on the engine harmonics. The harmonic tuning of a vehicle is rough when the throttle body is dirty. This causes the engine to begin to stumbling when going through the power band.

When the check engine light comes on, it is a sign that you should check the throttle body. It usually comes through the reduced power light or simple ‘check engine’ light. These are a few symptoms that your throttle body is failing; what you need to do is to clean up the part to make it return to its prime state.

How to Clean Car Throttle Body: Step-By-Step Guide

When you intend to clean the throttle body, first confirm if the operation mechanism. Does it need a throttle cable for manual operation? Electronic-operated throttle bodies calibrate on the throttle blades.

When you clean the throttle bodies, you will need to clean the blades; otherwise, it might cause the throttle body to malfunction. The ideal course of action is to carefully remove the throttle body before carrying out the cleaning process. Another option is to get an expert to have it cleaned for you.

You will need to put on gloves in order to protect your hands while cleaning the throttle body; materials you will need include the end wrench set, gloves, clean shop rags, air filter replacements. Others include a set of screwdrivers, socket set and ratchet, and more importantly, replacement air filters.

To start, remove the battery cables for safety measures. This is because when you’re working under the hood, you’ll be in close proximity to the connections. Next, take off the intake cubes, mass airflow sensor, and air filter cover. The next step will be loosening the air intake hose and taking off the connection from the throttle body; loosen the hose clamp that holds the connection in place before the hose slips off.

Take off the air intake housing from the engine. Place it in a corner till you complete the cleaning process. Change the air filter as most times, the problem with the throttle body is due to a dirty throttle body. Clean the throttle body with the throttle body cleaner by spraying the blades and the housing. Let the cleaner get into the parts for some minutes. Then spray on a shop rag and use it in cleaning the internal parts of the throttle body.

Check the throttle body edges for buildup so as not to miss an issue. After, check for any form of damage, and if there is, there might be a need to replace these parts. Check the control valve as well by removing and clean the inside housing; install back after the cleaning process. After cleaning the throttle body, install everything back, and then test the operation. Ensure you install everything in the reverse process of removal.

Final Thoughts

The throttle body is important and plays an integral part in the speed of the vehicle. There are times when it gets dirty and begins to malfunction. When you notice any of the symptoms of a failing throttle body stated above, follow the step-by-step guide provided. You can clean up the throttle body and make sure it’s properly functioning once again.
