P406 is a EGR code, EGR will also cause a knocking/ pinging sound when there bad. Very common problem. The position sensor inside the valve goes bad. Your going to have to replace the whole EGR valve and it can put out variety of codes from P0401 to P0406. The new valve will solve the problem and easy to replace, you can pick one up at Auto Zone and they can give you the step by step instructions to replacing the EGR with common tools. Good luck and hope this helps.
