There is none. All you have to do is check a part catalog. If it's not there it probably doesn't exist.
eg. rockauto.com

This code likely set because the throttle body was cleaned. If your scan tool has an idle learn function, use it, otherwise it will take a few drive cycles for the PCM to relearn the idle speed.
