knock sensor wire broke

[DJYoshaBYD]

The wire from the knock sensor came out... Is there any way to solder it back on, or do I have to spend 80 bucks for a new one? And the car is not running any different with the knock sensor off... I turned down the boost to 8 1/2 psi so I could drive it and not worry about knock... I read it was supposed to cause the car to run in "limp mode"... Any guesses why?

Bite the bullet and replace the knock sensor. How did you manage to pull the wire off?

My guess? I would think that because it can't read knock it can't adjust the timing accordingly. But I could be wrong.

I was yanking out my vac lines for my emissions stuff (they run under the intake manifold) and when I pulled out a bundle of hoses, a little y-splitter on the one of the hoses snagged it and pulled it out... sucks huh?

I would assume those wires have a certian resistance internally, therefore soldering them would alter the resistance. Giving you wonky knock numbers.

A good solder will add no difference to the resistance of the wire. Notice I said good. Just replace it will teach you not to just start yanking things. You had to yank pretty hard to pull the wire out.

not really...when I pulled it out looked quite old... Im already going to buy another one as soon as I get paid...
