I was routinely checking my car for faults, and found a P505 fault code. This is what I've been able to determine what that means:

Powertrain- Vehicle Speed, Idle Control, and Auxillary Inputs - ISO/SAE Controlled
Idle Air Control Motor Circuit Conditions
Key on or engine running, system voltage more than 10v, IAC motor active, then the PCM detected a short in one of the four IAC motor circuits for 2.75 seconds.

So, what now?? What do I need to look at to get rid of this code permanently? Can someone translate? This car is for sale, and it will be hard to sell with any code squawking.

Thank you for your help.
