Hey Guys. I am looking for some help. About a month ago my engine light came on. The code came up knock sensor bank 2 low signal. I did some research and found that water get down there an corodes the connection. I replaced both knock sensors and the wire harness from the dealer. Everthing was good and then today I got the same code. I was looking for some help. Anything you guys can think of would be great.

Thanks,
Jack
