I thought the magic is in the sensor, not the harness? What are the sensors being switched to?
Is this needed on cam swap as well?

i think he simply meant to change out the harness while your there so you dont have to pull the intake twice for separate problems..
and imo there is no need to mess with them unless your already there(intake off) and they looked severely corroded, or if they are showing problems..

any knock sensor codes will throw you into the low octane timing table as far as i know. We just battled this problem on my buddies truck. He replaced the knock sensors last year and just got the code back. Make sure you seal up the boots too, otherwise its only a short time until it happens again, especially if you wash your motor down once in awhile. BTW, his truck was only running 11* timing WOT because of the code, and it pulling timing from false kr from it.

I just read a comment from another member in the diagnostics forum that said that this code causes the computer to pull a constant 4* of timing. Ive got this exact code and I see 0 knock in my logs and the truck still runs great. Ill change it later in the summer when i get bored.

My rear knock sensor went out last year with the same code. Mine definatly pulled timing and I definatly felt a difference. What happeds with these knock sensors on our LS engines is MAJOR corrosion issues. People who wash and detail their engines on a regular basis will have this problem. Because the knock sensors are located below a cheezy plastic cap under the intake water will seep in and pool up in the knock sensor cavity. It mainly affects the rear sensor but if your changing them you might as well do both. The harnes can become corroded as well. If its messed up change it. Mine was alright so its still installed without any problems. What I did to hopefully prevent this from happening again is use RTV and built a dam to block water from going into the cavity. Its about 1/2"-3/4" tall and wide and wraps about half way around the sensor. Its worked out great and have had no problems since.
