The timing drive system consists of the following

1. Timing Chain (2)
2. Camshaft Sprockets (1,3)
3. Crankshaft Sprocket
4. Right Timing Chain Guide (Moveable) (6)
5. Left Timing Chain Guide (Fixed) (4)
6. Timing Chain Tensioner (5)

The camshaft sprockets are attached to the cam phasers which are attached to the front of the camshafts and are used with the timing chain and crankshaft sprocket to turn the camshafts. The camshaft position sensors target is part of the camshafts and is used with the camshaft position sensors to provide the PCM with valvetrain position information.

The timing chain tensioner is installed in the right side of the engine block. Using engine oil pressure, the tensioner applies constant pressure to the right side (movable) timing chain guide, which in turn applies pressure to the timing chain. Also as the tensioner extends, it rachet locks in position to provide constant timing chain tension.
