THe knock sensor is harder than changing out the egr valve. It's located right behind the intake manifold nearing the firewall. It looks like a mushroom, basically underneath the top hat is a diaphram (you can push up and should hear some noise)usually this stops working or there is a hole in a vacuum line which throws the code. Those are the things to check also you may be able to clean out the egr valve w. some cleaner and see if that works sometimes there is buid up inside.Just don't spray near the diaphram its rubber will deterioate. The KS is a pita, I gave up on it for now, I relocated the KS to the front of the block where the ks harness was held on by a bracket.I tried my best at it bought the swivel the angle on getting at the ks is unbelievable.
