Don't get to far ahead of yourself. First remove the EGR Valve its a round component located on top of the intake manifold in the middle. If your still unsure of the location, look at the Haynes manual for better explaintion and how to trouble shoot it. The EGR is either clogged with carbon buildu or is at the end of the life depending on how clogged up it is. If you need to replace it the cost for a DIY is agout $135.00 plus $6 for a new gasket, its fairly easy to replace about a 10-15 min. job. Addiationally, inspect and reaplce any of the vacuum lines that are bad. Do this first, then clean out the codes and see what happens. The knock sensor probably doesn't need replacing. The EGR cause the engine to vibrate out of wack thus triggering the knock sensor. Good luck

You need a metric box wrench to remove it. I'm not sure of the size it might be 10 or 11mm. Once you remove the EGR valve you can clean it with carb. cleaner and a wire brush gentley. Don't spray on the diarphram part, or non metal parts. Once its clean, place it back on with a new gasket. Inspect all the vacuum lines for brittleness or cracks and replace them as well.
