Abstract
Systems and methods for correcting an engine intake camshaft position and an engine exhaust camshaft position for a variable valve timing engine are described. In one example, intake manifold pressure of an engine is sampled while a motor/generator rotates the engine at a predetermined speed without fuel being supplied to the engine. A camshaft angle where minimum intake manifold pressure is observed is a basis for correcting camshaft position.
