Hi,

To access the knock sensor, you need to remove the intake manifold. Also, there are two knock sensors. If you look at the first picture below, I highlighted the bank one knock sensor.

You will need to remove the intake manifold. The pics below (starting with pic 2) are the directions and pictures for the removal and replacement of the intake.

I hope this helps. Let me know if you have other questions.

Take care,

Joe
