Knock Sensor...should I buy a new one for my new engine??

[87LtdT]

I have a sensor on my OEM 40k mile engine that I'm pulling from the car that I believe to be good...but I wouldn't mind purchasing a new one if there is a chance that mine is bad or moving it will cause it to fail.

Do these ever fail?? I sure don't now what makes them tick

Looking for experience/knowledge and advice

Thanks, Bob

It's rare that they go bad unless they are physically damaged. But if it makes you feel better you can replace it.
