Abstract
Systems and methods for operating an engine that may be frequently stopped and restarted are described. In one example, an engine is rotated in small crankshaft angle increments and stopped after the engine is rotated through a predetermined actual total number of crankshaft degrees so that the engine position does not change when the engine reaches a desired position.
