Knock sensor harness... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So I have this knock sensor harness but I'm not sure if it's okay or not.. When the car was running, I was getting knock sensor codes on the obd scan.. When removing the engine I saw that the end that plugs into the main harness wasn't grounded and assumed that was the cause of the code.. Now that I'm putting the engine back together, I found that the plug on the knock sensor side doesn't have a lead for the ground. After removing the wrap from the harness, I found that the ground was wrapped around the sensing wire(???)... Is this what it's supposed to do? I don't feel like paying $80 for a new piece of cable... Here are some pictures to better describe what I'm talking about..

(sorry about the depth of field..

ops: )

That's how it's made, nothing wrong with it other than being dirty. Knock sensor codes are tricky to diagnose as it's rarely the sensor that's bad.
