Hello,

The bank 1 sensor 1 oxygen sensor is the one before the catalytic converter, at the exhaust manifold. It is the left side oxygen sensor.

Here are some helpful articles:

The knock sensor is located on the center of the engine block (see diagram). You will have to remove the intake manifold to access the knock sensor.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
