O2 sensor input output I just replaced my O2 sensors. Bosch 
Before I installed the new sensors I checked the output to the sensors at the plugs.
Both read : 12v white 0v white 4.54 blk and 4.95 grey
Knowing that both whites are for the heater and the others are for signals back to the PCM.
I think that is about correct but Id like to make sure with all you LS1 guru's
