Knock Sensor Issue So my Z28 threw a 332 code which means Knock sensor, so I check the sensor and its fine, so is the connector... I did a voltage test from the connector to about 8 inches up (as far as I can go) and there is no voltage...
Now before I rip stuff apart to locate the ECM I need to know where it is first and if anyone has a schematic or diagram on the wiring or if they have a code or they are color coded if there is a chart for it. Im guessing the wire came off the ECM (well its wishful thinking because a little solder and its good to go) if the wire is ok after I trace it then its a bad ECM which sucks because I cant buy one tonight.
If anyone can help it would be greatly appreciated. Thanks guys

Make sure its not grounding anywhere
