2001-CamaroSS-LS1

Just got my Camaro SS back to day from getting my LS1 rebuilt...driving around tonight i got a P0327 knock sensor 1 low circuit imput...is this because im using 93 octane? are they bad? or is it because i have a small exhaust leak and its picking it up as a knock? the link will be fixed because im getting my SLP LM1 put on. Any help would be great!!

Thanks guys!

fix the exhaust leak and see what it does (thats the easy/cheap fix). 93 octane doesn't hurt.

Did you wash the engine recently? Chances are you'll have to replace the KS.

Or the harness for the sensors got pinched.

and exhaust leak couldn't cause knock... was this light on immediately after the rebuild? seems like an installation issue

If the harness was pinched you'd probably throw both codes (PO332). Depends where it's pinched I guess.

I had both of my knock sensors **** out on me. Its probably due to them being old and needing replaced. I drove on mine f***ed up for over 6 months and never noticed a differnece. Have fun replacing them. If you do one then do them both cuz the manifold has to come off.

Throwing the KS code(s) causes a constant 4 degrees of knock retard so it's not something you want to live with. Yes, definitely swap both.

wouldnt be a bad idea to have the harness for them also. I just changed mine and cracked both connectors during removal. They are hard to reach and crack easy from the heat. its like a 50 dollar part from the dealer

I was going to mention a harness since I messed mine up trying to remove it and had to replace it (same as you, the connectors), but I thought maybe I was just careless. Actually I had to replace my harness twice. The other time it got pinched under the intake, I was careless routing it before I replaced the intake.
