OBD II fault code P0505 is defined as “Idle Control System Malfunction”, or sometimes as “Idle speed control (ISC) system –malfunction”, and is set when the PCM (Powertrain Control Module) is unable to control, or maintain the engine idling speed at a specified RPM. Note that regardless of slight differences in the wording of various definitions of code P0505, this code always refers to the PCM’s inability to maintain or control the engine idling speed.
