-after you change the part you have to reset/clear the code
-this can be done by either:
(1) using the OBD2 code reader that Autozone used OR since option 2 (below) is very quick
(2) disconnecting the battery for about 30 seconds (this will delete all codes/radio presets/etc) but it will also clear the 'check engine' code
-this is what I do AFTER i write down my radio station presets :)
-hopefully the new EGR valve resolves your issue after you CLEAR the code
...but that code just means a an insufficient amount of Exhaust Gas recirculation (pressure difference) used to keep the emissions in check
-if it comes back, then there are a few other fixes to try also
-let me know if you need further assistance
-please remember to rate me `fix-ya`if it works

po505 idle air control if this is the code all hondas do it eventully, small problem easy fix u have 2 choices either remove the idle air control motor and clean the inside of it u will find it's black and the spring inside is stuck clean it with carb cleaner or gum cutter any parts store will have this it's a dirty job it will work for awhile but to replace it is recommended its not expensive for a new one which u can get at any autoparts store autozone,advanced,napa etc. there is only 2 bolts in most cases maybe 3 i doubt it though if u go online t google and type in th eyear make and model and engine size in ur case it's a 3.0 v6 and look for idle air control locations u'll find it to do this job a shop will charge u anywhere from 100.00 for diag to retrive the code plus the part and the labor so about 250.00-375.00 it will only take u honestly maybe 15 minutes to perform only tools needed are a 10 millimeter wrench there is only 1 connector to disconnect and ur done if u do this u will still have the check engine light because u have not cleared it from the computer to do this just disconnect the negative battery terminal (the black one or has a neg sign - don't disconnect the positive side +)for 5 minutes then reconnect and the computer will have reset no more light. good luck it really is that easy

No-one is ever particularly happy to here this, but this is the way it is; we do have to keep in mind that the original idea of codes on radios was to prevent people who steal them from being able to use them.
So, if an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code (some people say that they have found the code on a sticker inside the glove compartment, but I wouldn’t count on that). Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The serial number will come up in two sets of numbers.)
Some older vehicles (model year 2003 and older) require a visit to the dealer in order to retrieve the audio unit serial number (or you can remove the unit and get the serial number from the back of the radio). Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.
Here is the URL for the Honda Owner page. If you register (no charge) you are able to get radio codes using the VIN number of your car, the serial number of your radio, and the Phone Number and Zip Code that you give them when you register.
Hope this helps you with the process.
