Hello, my name is ***** ***** thank you for using just answer. The site will prompt a phone call, but that is not always necessary. If it is necessary later in the conversation, I will propose it. I am sorry you are having this concern, but I will do my best to assist you.

Hopefully there is no noticeable knocking or clunking coming from the engine ( rod knock, motor mounts, etc). Knock sensors are sensitive to outside electromagnetic activity. If you replaced the knock sensor with a O.E. part, and the issue remains, most likely it is an issue with the shielding, meaning you need to replace the engine wiring harness. I do not see any applicable technical service bulletins or recalls for this concern. Hope this helps, thank you.

the engine wiring harness need to be replaced.

That's a good possibility. My repair information shows this as being a issue. The only way to confirm it would be to use a oscilloscope and watch the knock sensor signal.
