Putting motor back in... found loose wire??

[Harriz801]

Well today i was putting my motor back in my car and i was looking underneath it and i saw that a wire had been pulled out of somewhere... where i found out where it came from i just dont know what the heck it is... It came from a bolt that actually runs right into the block on the back side of the motor... its right under the intake manifold and by all the freeze plugs... The wire ran into the middle of this bolt.. when i took it out alls it was, was a bolt... its a red wire if that helps any.... Thanks for the help in advance....

If it helps any i could upload pictures of where it goes and what it looks like.

yep. totally the knock sensor. make sure you hook it back up and put it right in the middle of cylinders 2 & 3.

Put it back in, and don't run the car without it. Be careful not to overtorque it either, I've seen many a knock sensor killed that way. I believe that it's 17 ft/lbs., but check the manual.
