ABSTRACT:
A method of diagnosing an idle speed control system for an internal combustion engine in an automotive vehicle includes the steps of determining whether a plurality of conditions are met for the idle speed control system, ending the method if the predetermined conditions are not met for the idle speed control system, determining whether a difference between an engine speed and a target idle speed is greater than a predetermined threshold value if the predetermined conditions are met for the idle speed control system, and concluding that the idle speed control system is functioning properly if the difference is not greater than the predetermined threshold value.
