i hava a magna charged ctsv that iv replaced the knock sensors and the harness but still get the po332 code''knock sensor'' and cant seem to fix it...can the knock sensors be tuned out? when the light comes on it pulls all the timing and kills my performance...any ideas would be great!

Yes you can turn the knock sensors off with tuning but keep in mind they will no longer let you know if the car is knocking at all.

Did you check the knock sensor harness if it has a pinch?

Yes replaced the harness with new oem harness...i think im just gonna have the knock sensors tuned out...i have a basic setup...blower and headers so with a good safe tune and premium gas i think i will be ok without them

No, you wont.

I wouldn't tune a PD blower in a nice car like that with no knock sensors that sees the inconsistencies of pump fuel. The absolute best approach is to have the repairs made.

Agreed. Something is wrong, fix it or plan on buying internals instead of simple bolt-on's.

Hey.. lets tune out the knock sensors on a boosted car... While we are at it... lets install those cross drilled brake lines.


Fix the problem.

you want your knock sensors to be operational.

Maybe an issue with the tune and its actually detecting knock? Also, where did you get your knock sensors from? Check the resistance range on them, I've gotten a knock sensor in the past from Napa, wrong resistance. After going crazy for a few weeks I got desperate and went to the dealership. They figured it out and stabbed the proper one in.
