2002 honda civic code p0505 - Civic Honda Cars & Trucks

SOURCE: Engine code P0505 for 2002 honda odyssey

p0505 is directly related to the idle air control valve (sometimes called the rotary valve) i cant count how many of these i have replaced on hondas. It is located directly under the throttle body so it can be difficult to replace. I would recommend you having a professional replace this due to the difficulty of the valve removal

the idle air control valve should be checked for operation both mechanically and electrically, it could be defective. cost depends on which trans you have auto around $230.00 for the part, manual around $150.00 for the part. at those prices I would be darn sure it has a problem before replacement, or find one from a salvage yard in better shape.

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
