I actually had my sensors replaced when I first bought my Z28. I test drove
and everything was fine, but they detailed it and after I bought it and drove
it off the lot, the ses light came on.
I turned around and took it to them and asked them to scan it and they said
it was the knock sensor (don't remember exact code) They deleted it and
within 30 seconds of turning the car back on the code came right back. Since
they had just pressure washed the engine (after telling the detailer NOT to)
they replaced both of the sensors and put rtv around them to help divert water
in the future. They said if it wasn't their fault it would've been $400. Since
they changed them I haven't had any problems or codes.
My suggestion, replace the sensors...
Hope this helps
