Timing chain set

This chain is located at the back of the cylinder head, connecting the two camshafts. The upper chain track of the tensioner is under high load and tends to break. This is caused by the angle created due to a stretched chain.

Failure of the chain tesioner will in many cases cause the fault code: P000A/000010 – Camshaft A (Bank 1 Intake): Positioner Slow Response.
