Knock sensor location

Hello,

It looks like it is under the intake manifold. Here is a diagram of the location (below)

You will need to jack the car up to get to it.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

You have to remove the intake manifold to see them. They screwed onto the heads.
