SOURCE: 92 lexus es300 knock sensor
Need to remove the upper and lower air intake manifold. There are two knock sensors for the front and rear pistons banks. If you plan to do this yourself it is about 1 to 2 hours. While you are at it, there is a short coolant bypass hose sitting in the same spot, replace it. Another problem with the knock sensor is the wire harness used to connect the two knock sensors into one connection sometimes wears out and contacts the metal on the engine causing false signals to the ECM, so replace this cable also.
Just did this last summer on my 99 ES300. Pretty easy.

mcdevito75 here, I believe it"s under the hood a s you look on the engine the fuse box will be on the right side by the inner fender., Best Bet Check with any local auto parts store for it"s location.

SOURCE: I removed the intake manifold,
Thats crazy, they should be underneath the manifold plain as day. I know this isn't the solution you were looking for, but that is exactly where they are located???
