Rewiring knock sensor, yay or nay?

I would also start with an ohm check, both threw the wire and any shorts to ground. If you were to re-wire it make sure you have a insulated casing that will shield the wire from electrical noise, tin foil wrapped around the wire with electrical tape over that then ground the tin foil on both ends to a clean chassis/engine ground. Also keep the wire as fare away from ignition and CAS and other ground wires as possible.

This.


We had to re-wire a plug back on the harness of my friend's 92 TSI so we could hook the knock sensor back up. It's been working fine so far, but I don't think re-wiring would solve phantom knock issues or an over-sensitive sensor. I have heard of using plumbers tape on the threads in an attempt to try and cushion the vibrations a bit more, however.

You remember the old how to see if knock is real, Higher octane fuel if it goes away it's real. The car on corn had no knock last night.
200,000 miles=Knock on pump.
