02 silverado knock sensor problem - 3/26/2007 12:51:33 PM

I have an '02 silverado with the 4.8l engine and I am getting a P0332
code "knock sensor signal frequency outside normal range". I have
cleared it several times but it comes back withing a few minutes. Does
this mean the sensor is bad or is it telling me the engine is
knocking? The sensor is under the intake manifold so it is a faily big
job to replace it. What else should I look at? Thanks for any help.

take the knock sensor out and wrap a bunch of Teflon tape around it... like allot almost until you cant get it to screw in, it is an old trick we used many moons ago to get them to not be so sensitive to GM's piston slap issues
