bad o2? What exactly does it mean when one of your o2 sensors is reading .455 mv at any speed? I was trying to figure out this a-tap when I noticed that the driver side front o2 was stuck on this reading no matter what I did. I haven't seen any codes or anything. Sean

Re: bad o2? .450 is flat reference voltage like when it's not warmed up or not operating. You should be throwing codes though if that were the case?
I had this problem when my O2 heater circuit wasn't working. Could be a heater circuit or a bad O2.
