Yes I've searched, and have found pics of "similar"motors (7m, 1jz)posted but not our sc 300 motors...would just like someone to describe where the knock sensor is located.thanks cl

 

driver side of the engine under the intake manifold. They sit a little higher on the block.

 

I was kinda guessing that. is it closer to the front or back?

 

Please stop making new threads and use the search botton , it took me 5 seconds to find the answer google.

the top one is the knock sensor you have 2 of them front and back the front one is right on top of the oil filter housing the rear one is by the starter on the side of block you need i think a 24 mm deep socket to remove it.
