1. Prepare the working area
Before I show you how to clean your idle air control valve without removing it, you have to prepare your working area. It may sound not important, but please only work when the engine is cold.
2. Locate the idle air control valve
If you haven’t cleaned an idle air control valve before, you might have a hard time locating it. Start from the filter box and work your way up. The filter box is a large box that holds the air filter.
3. Remove the filter box and the air duct
In order to disconnect the filter box, you will have to disconnect the clamps that are holding the filter box. Next, if your vehicle has a MAF sensor, disconnect the wiring that goes into the MAF sensor.
4. Disconnect the clamps that connect the air duct to the throttle body
Undo the clamp that’s holding in the air hose to the throttle body by unscrewing the screws and disconnecting the clamps. Then, pull out the air hose and store it safely with all of the screws that you have just removed.
5. Locate the passage to the idle air control valve
With your throttle body exposed, you will be able to see a small ”hole” or passage that is located on the inside of the throttle body. This ”hole” or passage allows the air to bypass from the air duct into the engine when your car is idle. Inspect the hole and see if it has visible carbon build-up or something that may restrict the airflow.
6. Spray the hole with throttle body cleaner
Get yourself some throttle body cleaner. It doesn’t have to be fancy. The one that I am using is listed on amazon.com ( see the price of throttle body cleaner here ). Then with a plastic wire brush, clean the passage or passages even more. I got this cool plastic wire brush on amazon.com.
7. Reconnect all of the components
After we clean everything up it’s time to put everything back together. The reconnecting part is going to be a reversal of removal. Just make sure that you don’t skip any steps. Reconnect one side of the air hose to the throttle body and secure it with screws and clamps.
