Can you tell me where to find the knock sensor bank 2 on my car; and, can I replace it myself as a novice? I can’t seem to find any videos replacing it on YouTube, for my car listed above. Thanks! Yvonne

Hi,

The bank 2 knock sensor is near where the oil dipstick is located. As far as replacement, the worst part of the job is draining the coolant. It has to be done. And, yes, I feel you can do it. I'll help if you run into trouble.

First, here is a link that explains how to drain and flush a cooling system. You can skip the flush portion and just follow the draining and refilling procedures.

As far as replacing the knock sensor, I attached specific directions below. Take a look through them and let me know if you have questions.

Take care and let me know how things turn out for you.
