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.

What is code for P0505 2002 BMW 330ci


Do you understand what exactly sets a P0505? It is not an electrical code, it is purely performance. The code sets when it can't get the idle speed within +200 / -100 of the target for more than x seconds, and it takes a failure in two successive drive cycles to set the code. ANYTHING that can cause an incorrect idle speed can set this code. Vacuum leak, dirty IAC, etc.

The TCS and check engine light both came on my 2002 honda odyssey? Is it the O2 Sensor? Or can I just reset the lights? The engine also idles very low when the vehicle is stopped at a traffic light. No...


Don't reset the lights without getting the DTC's or diagnostic trouble codes from the car's computer. An autoparts store can hook up a diagnostic code reader for free. With the codes in hand, you can start to diagnose your issue. You can then reset the lights to see if the codes return.

Iac location on my 1999 honda odyssey?after engine warms up-idle runs up and down from 900-2100 rpms.problem occurred instantly.scanned engine P0505.no vaccum leaks.


The IAC is located under the throttle body.

When engine gets hot, idle is up and down with the engine light on. OBD code gives a P0505 code.


per this address "http://www.obd-codes.com/trouble_codes/" p0505 is a "IAC (Idle Air Control) System Malfunction" it gives some good suggestions to look at to find a solution for your problem.

When in park honda odyssey revs up and down between 1000 and 2000 RPMs


is the check engine light on also? it sounds like the idle air control valve is bad. this controls the idle of the vehicle. when it is stuck open it causes too much air into the engine and causes it to rev. when it gets to a set rpm, the pcm cuts fuel. then it turns the fuel back on, then the engine revs, then it cuts fuel........code p0505 will prob be set

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
