How to Clean a Throttle Body on a Car

Introduction

A throttle body is a key component of a car’s engine, responsible for controlling the flow of air into the engine. Over time, the throttle body can become dirty and clogged with carbon deposits, which can lead to a variety of problems, including rough idling, poor acceleration, and increased fuel consumption. Cleaning the throttle body is a relatively simple task that can be completed in about 30 minutes.

Tools and Materials

* Throttle body cleaner
* Rags
* Screwdriver
* Socket wrench
* Gloves

Safety Precautions

* Disconnect the negative terminal of the battery before starting work.
* Allow the engine to cool before touching the throttle body.
* Wear gloves to protect your hands from harsh chemicals.

Step-by-Step Instructions

1. Locate the Throttle Body

The throttle body is typically located on the intake manifold, which is the part of the engine that connects the cylinder heads to the air filter. The throttle body will have a large, round opening on one end and a smaller, oval opening on the other end.

2. Disconnect the Air Intake Hose

Using a screwdriver, loosen the clamp that secures the air intake hose to the throttle body. Carefully disconnect the hose and set it aside.

3. Remove the Throttle Body

Using a socket wrench, remove the bolts that secure the throttle body to the intake manifold. Gently lift the throttle body off the manifold and set it aside.

4. Clean the Throttle Body

Spray the throttle body cleaner liberally onto the inside of the throttle body. Use a rag to wipe away any dirt or debris. Be sure to clean the butterfly valve and the throttle plate.

5. Inspect the Throttle Position Sensor

The throttle position sensor is a small, black sensor located on the throttle body. Inspect the sensor for any damage or wear. If the sensor is damaged, it will need to be replaced.

6. Reinstall the Throttle Body

Place the throttle body back onto the intake manifold and secure it with the bolts. Tighten the bolts until they are snug, but do not overtighten.

7. Reconnect the Air Intake Hose

Attach the air intake hose to the throttle body and secure it with the clamp. Tighten the clamp until it is snug, but do not overtighten.

8. Reconnect the Negative Battery Terminal
