Default P0330 came back

I had a mechanic replace the Knock sensor, Wiring harness, and gaskets needed, and for 600 miles I had no problems. I used only OEM parts, not cheap knockoffs.

Today the P0330 came back. Same bank two code it was throwing the entire time. I have no idea what could be causing this problem. I'm sorry if this has been answered somewhere before, but I'm in a serious predicament. I was not expecting this problem. I need some advice on what to check, and prepare to shell money out for next.

Don't dismiss the possibility that even a brand new Lexus part could be defective.

Although a lot of work, If you get inthere again, interchange the 2 knock sensors, and see if the problem follows the sensor. Also double check your electrical connections.

Check the vvti controler for that bank could be getting stuck causing the sensor to pick up knock.
