I am having an intermittent knock sensor issue. Can I get a diagram as to where they are located? Both banks?

I would check the electrical connectors for corrosion as well. The bank 1 sensor is right behind the alternator while bank 2 is behind the turbo. This sensor can get heated from the turbo and make it stop reading so keep that in mind. Here are the locations of both knock sensors. Check out the images (below). Please let us know what happens.
