The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.

Engine would crank, but wouldn't start. Intermittent condition for months. Engine ran ok if it did start. Replaced camshaft position sensor. No problems since!
