Hey whats up everyone, I really need some help. I have a 2003 Honda accord LX 2.4L. The car is not idling good at all, the check light is in and everything. I put it on the computer and it give me the code P0511 and it says "Idle Air Control Valve Circuit" What does this mean? Is it the wiring bad or it's the idle air control valve? I would be grateful for the help.

Try cleaning out the idle air control valve and see what happens.

So that would be the first step for you to take? I am kind of confuse, because the guys at honda says, the that I got, could mean that the wires to the idle air control has been damage, OR The idle air control valve is damage. They also said that they have never seen a 2003 honda accord with a idle air control valve problem. So I should check the wire loom first. So what you think?

Either you clean or replace it and also check the wiring back to the computer-don't work bring it to the Honda boys its their product. As for me I'll start with the IACV then go from there.
