Knock Sensor 1995 ZR1 - ZR-1 Net Registry Forums

I had a knock sensor code on my 1993 when I purchased it last year. No burned connector like you. I replaced the knock sensor with an AC Delco unit I got from Jerry?s and problem solved. One check I did before changing the sensor was to check the continuity of the wire from the knock sensor connector to the ECM plug. Maybe check that to make sure your wire/connector are good, easy to do, check the service manual for the terminal on the ECM plug, I do not currently recall which one it is. Good luck,
Brian
