On a dodge neon 2004 the code reads P0507 idle control system. Is that a sensor?
No, it's not a sensor. The engine computer controls idle speed by an "actuator" called an IAC -idle air control -motor or valve. It sits right on the throttle body where the air hose, the big boot, connects to the top of the engine. It controls the idle air passage-smaller air passages besides the larger throttle plate opening- according to computer command.
Probably your IAC motor or valve has a problem. A good cleaning often helps. Remove it and scrape off gently the deposits. Don't push the end piece, the pintle, back and forth, and don't spray cleaner up towards the little motor. Check the air passages where it mounts on the throttle body and clean as best you can. If it needed cleaning, take off the big boot and use a sensor safe cleaner, like throttle body cleaner, and old rags and old toothbrushes, and clean out the inside of the throttle body and the big butterfly valve, the throttle valve, inside. Note that when it is at rest, no gas pedal giving it gas, the throttle valve is almost completely closed. Those separate air passages in your idle control system, what the IAC motor controls, is the only way for the engine to get enough air to keep running. If they clog up, or the valve or motor doesn't work anymore, anyway the computer sees a wrong result from engine rpm sensors, and what it is commanding from the IAC motor, so it alerts you the problem is in the...in the idle cntrl system. Have at it, friend. It's either do it yourself or pay labor costs for a pro.
