My 03 odyssey has a trouble code P0505 - Idle Control System malfunction (no other trouble codes). I was going to replace the Idle Air Control valve but I would like to know if there is anything else I should try before doing that.
The symptoms are as follows: Idle fluctuates between 1000 and 1500 rpm when in park or neutral. Does not fluctuate when in drive or reverse. Also, idle fluctuation stops when I turn the steering wheel back and forth.
The problem started after I picked the car up from the body shop. They replaced the windshield and fixed the rear bumper. I don't know if they had anything to do with the problem, but that's when it started.
Thanks for the help.
