I have a code p0325 knock sensor 1, circuit bank 1 or single sensor problem

Take it back! If you bought it as is do this. Retrieve radio code and any other preset. This is called a "hard reset" and will return all modules to their factory settings, disconnect both battery cables and touch them together for 30 or more seconds then reconnect and see what happens. I would be interested to see how this turns out. I hope this helps. Take care. If you have more questions for me or want to let me know how you turn out use testimonial and it will show up in my email.

sorry would a play with this to know for sure ,check the wiring plugs onto the sensors to make sure their not full of oil or corroded

I hopes this helps you.
Replace or fix these two items should do the trick.
It's hard to diagnose a car over a computer.
