How to Clean a Throttle Body

Introduction to cleaning a throttle body

When it comes to maintaining car hygiene, cleaning the throttle body is an essential task that should not be overlooked. The throttle body is responsible for regulating the amount of air that enters the engine. Over time, it can become clogged with dirt, grime and carbon build-up, leading to reduced performance and increased fuel consumption.

To ensure that your vehicle runs smoothly, follow these six steps when cleaning a throttle body:

  1. Remove air intake duct
  2. Unplug electrical connectors
  3. Detach any hoses or cables connected to the throttle body
  4. Spray cleaner onto a cloth and wipe the inside of the throttle plate open while holding it with your hand.
  5. Spray cleaner directly into the opening of the throttle body assembly
  6. Reassemble everything in reverse order.

It’s important to note that cleaning frequency depends on driving conditions. If you’re often driving in dusty areas or traveling short distances frequently, you will need to clean it more frequently than usual.

Pro Tip: Use genuine manufacturer-recommended products when cleaning the throttle body as they are designed specifically for your model.
