    2001 gmc z71 5.3 w ls2 cam need info

    I am new to this site and would like to start by saying thanks in advance for any help
    which I may receive!
    I built a 5.3 for my 01 z71
    I put the flat top pistons in it and a set of 243 casting heads
    I also put a ls2 cam and the ls2 front cover with sensor on it I changed the wiring
    as ness and now I'm setting a p0342 cam sensor low voltage code I've never had any
    issues with the cam sensor wiring before now
    please help as I'm a little confused 01 is a 12v system and the ls2 sensor is a 5v
    setup what can I do?

    Did you swap the cam wires when you moved sensor to front

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    yes it was setting a p0343 high voltage code
    now I'm getting the 342
    2001 is a 12v system the new sensor works on a 5v setup
    is this my issue?

    so I called Lingenfelter and spoke to a tech about my problem! I used a newer one bolt cam and sprocket
    which was a mistake its a 4x sampling a 3 bolt cam and sprocket is a 2x and no one makes a 2x one bolt sprocket
    at this time so I either live with it or I have to change the cam and sprocket
    does anyone have a ls2 stock cam that is a three bolt setup? I'm on a strick budget expecially since
    I'm a $1000.00 in to this motor already

    Ls2 cam sprocket is all you need for a Gen3 pcm. its the 1 x setup and is a 3 bolt setup
