What would cause the O2 Sensor Voltage to be high ?
its 0.28v and the others are 0.05v Now these are all new with less then 100 miles on them,This is only happening on Bank 1 Sensor 2. Is it possible the new one is bad ? Also when i replaced it the old one had signs of antifreeze on it, will that destroy the sensor in a very fast manner? The head gasket issue has been delt with.

Well I would say you either
A) Have a faulty O2 sensor
or
B) You have a short in the O2 sensor circuit
The high voltage reading means rich so you could have either a catalytic converter problem or your just running to rich which is very unlikely since no other sensor picked this up.
Also I'm assuming that your car threw an MIL that told you this?
I would swap the bank 1 sensor 2 with the bank 2 sensor 2 and see if you throw the code for the other side...if so then you know it's the sensor, if not then you have problems elsewhere...
Hope this helps...

And...no one knows.
Anti-freeze (w/silicone) can damage oxygen sensors.
Does the car show a code for sensor malfunction?
I also don't think you can compare the outputs for the primary ('wide-band', current based) and secondary oxygen ('narrow-band', switching type, voltage based) sensors.
