Its the IAC idle air contorll unit its on the air horn and controlls the air flow at idle This code is saying that something is malfunctioning it is not saying at what RPM it is happening at there is 5 or 6 differant codes for this and they run from P0505 thought P0509 but if you are geting P0505 i would just replace the unit but check the connection to it first it may be a bad connection it dose get weather and heat and that cerates problems with contacts

well the ecu try to control the idle but if there is a leak on the intake maniful after the trotlebady it can not control it check for vamum leak may be a hose the pcv valve hose on the intake

HI THIS IS Common cause of surging idle and the code P0505 is a sticking Idle Air Control (IAC) valve. Refer to Honda TSB #04-007 for updated part number. Hope this helps replace your IAC.
