YES, its possible... this valve is located at the side of the intake chamber or plenum, downstream of the throttle body. Also, for the year, its possible that some modes present this device as "one unit"; try to look and ask in other Honda shops oa Parts Sites like

Here we will describe the basic process for replacing your idle control valve. Please note that for different cars and trucks the process will not be the same. Generic steps to replace your idle control valve:
- You will want to begin by first gaining access to the idle control valve. In order to do this you will need to remove the air filter assembly, along with the air mass sensor and the air mass meter boot. Once you remove this whole assembly, you should have easy access to the throttle body.
- Remove the four bolts that secure the throttle body to the intake manifold.
- Usually on the bottom of the throttle body, on fuel injected cars, there is a idle control valve. To remove the old valve, simply unscrew or unbolt it.
- Bolt on the new valve, and reinstall everything. Make sure you replace your throttle body gasket at this time.
How can I tell if I need a new air idle control valve?
If your car has a rough idle or the idle cycles up and down, then chances are that you have a bad idle control valve. On modern vehicles, the purpose of the idle air control valve is to regulate your idle, and keep the idle smooth. The idle valve is controlled by the ECU or the computer, and when in gear the idle should be between 800 and 1000 rpm, and not in gear, between 700 and 900 rpm.
