Thread: TBSS 06 and 07 knock sensor

    TBSS 06 and 07 knock sensor

    The knock sensor sensitivity on a stock 06 is 400 mV, the 07 (mine) is 129.95mV. It's the same ACDelco part#. The multipliers are a bit different. Are the 06 vcms just set to be less sensitive from factory? If so. would it be "safe" to raise it to 300 or so on my 07? I seem to log spark knock for the slightest thing. Has anyone seen/noticed this before?

    I would call it "safe" I think. GM changed lots of junk on the 6.0L's such as Block/Heads/Cam combo. They also went to a better warranty so they increased the Knock Sensitivity up just to be safe on their end.
