Getting P0330 code for bank 2 knock sensor. How can jump the wire from bank 1 sensor. I need to identify the wires at the ECU.

It sounds like the sensor is out. Here are the complete engine wiring diagrams so you can see how the system works and the location of the knock sensor under the intake manifold:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Cheers, Ken
