    1998 Z28 Knock Sensor

    I know the knock sensor harness exits the at the back of the intake manifold. Can anyone tell me exactly where the connector is once the harness exists the manfold. I want to clean the connector and do a resistance measurement on the sensors before a change anything. I'm geting a code 0327,low signal, and there is no timing retarding occuring. I have looked all over for the connector but I can't find it. A picture would be great.

    It is at the back of driverside valve cover, use a flash light and you will find it clipped on to bracket. Work it and you can get it up at back of Intake to unhook.

    Finally found the connector. Disconnected and measured the resistance on both wires. According to my info, #1 is bad. We cleaned the connectors and put it back together. Reset the code but it came back and then the next day went away. I suspect something else in the connection. I tried to find the sensors at the parts store (even chevy) but they all show 2 different P/Ns (early design and later design). How can you tell which one you need without removing the intake manifold? I had them try to search by VIN but that didn't help.
