Camshaft position sensor and crankshaft position sensor deliver input signals to Engine Control Module (ECM). Camshaft position sensor is located at driver's side front corner of cylinder head, just in front of intake manifold. Crankshaft position sensor is located near crankshaft pulley, just above oil pan on driver's side of engine. ECM may use input signals for determining ignition timing (spark advance), and for controlling fuel injection system and heated oxygen sensor system.
