The code P1509 is a problem with the idle air control valve or circuit. The most common failure is an idle air control valve internal short. It is possible that the valve may need to be replaced. I recommend having the system diagnosed by a mechanic, like one form YourMechanic, to inspect the issue. They will be able to let you know what is in need of repair and replace your idle air control valve if necessary.
