Probably won't help. Idle Air Control valves are blamed probably ten times as often as they are at fault in Honda engines. It is mounted on the side of the throttle body and has a connector with wires instead of hoses.

You don't mention why you are interested in the IAC valve, but if it is because of idle hunting (revving between about 500 rpm and 1500 rpm smoothly and rhythmically), a bubble in the coolant is by far the most common cause. If the coolant is changed and not bled the normal idle speed can't get hot coolant to the Fast Idle Thermo valve (FITV) so it figures the engine is cold and the valve opens to raise the idle. That raises the coolant to the FITV, which then decides the engine is warm so the valve closes, dropping the idle speed, over and over. Burping the coolant, by opening the bleed nipple on top of one of the radiator hose housings at the engine half a turn until a steady stream of coolant comes out, should stop that. Do it with the engine cold.
