You have two knock sensor's, both sit under the in-take magifold on top of the engine, you will have to remove injector rail and in-take.

its on the driverside in the block under the exhaust manifold.

Under the intake manifold. Make sure you get the harness for the knock sensors. and clean out all of the rust and junk you're going to find donw in the holes before and after you replace the sensors.
