did you unplug or plug in any of the conections while the Key was on??? That can cause a voltage spike and damage the components... Have you put another sensor on it???
Yes you can check the voltage and the resistance on the sensors, but I dont have any of that info in front of me right now...

I am going to check voltage and resistance later tonight. I wish I had a service manual to tell me what it is all supposed to read.

I just hooked it up to a GM diagnostic reader. After warming the truck up, Bank 1 sensor 1 is only reading 35 at idle. Bank 2 sensor 1 is reading a little over 400 and appears to be working properly on screen. MAF was reading -27 degrees. So does anyone think that the MAF could be the problem?

and the MAF sounds like it needs to be replaced...
