picked up an ls1 swap and drove a couple miles some backfire and threw a few codes engine light the one that sticked out was p0332. I then logged it knock sensor was not reading at zero. Will I need to get a new knock or is this caused by the tune, I did not tune this it was already tuned and person I bought this said there was a cam but sounds too quite and I dont believe can someone confirm if the tune was edited to compensate with a cam and also cause the knock to be at 0 or just need to replace sensor. Thank you I'm still pretty new at this as this is all a new language to me.
Also I had p1133 02 sensor but sensor looks to be functioning right?
