I checked for continuity to the chassis and it is directly connected. My guess is that you can actually put that wire anywhere on the bare frame or engine and it would still behave the same. I fired up the car and didn't notice any difference either. For some reason I thought that it was specifically fed to a resistor pull down source at the ecu or maybe the negative signal lead to the cam position sensor haha. Guess I was wrong.
I traced it all the way back about 2 1/2 feet towards the passenger side and it bundled to other multiple grounds. replaced it all and no problems so far.
im having an issue with this wire, i just put my engine back together, and i went to fire the var up and the wire heated up and melted the casing right off it
Last year, K20 to Evo verified that it is connected to a collection of grounds. You have/had a short. Somewhere on that wire where it is seeing positive voltage. I would start by peeling back the insulation and checking the wiring harness for any tears or cuts in the loom where this wire travels.
Good question. If that was really the solution to the problem, then that means that the tiny cam sensor ground wire was picking up all the current that the thicker transmission ground was supposed to handle.
When you try to pass high current through a small wire you get a lot of heat due to the high resistance of the small wire i.e. 12v=IR.
That could have been the cause of your problem. I say drive it around and check it often until you feel comfortable that the problem is fixed.
If you really want to be sure, I would disconnect the cam ground wire from the engine and check for continuity between the wire and the chassis using a multimeter to make sure it wasn't severed then bolt it back up.
