First you sould be aware that all the O2 sensors do is make you aware that you have a problem, Changing the O2 sensors does not cure the problem .. in fact ,, it's only confirming that the problem is still there. A Good On Board Diagnostic will tell you the sensor that's triggering the alarm ... by knowing what sensor is sending the alarm ,,you can determine the problem . If it's before the catalytic converter it's an engine issue ,,if it's after then it's a converter issue

The Codes were P2195 and P0031

So, disconnecting the battery will not help? There were some people on here that stated, disconnecting the battery helped clear the codes after changing the O2 sensors and they have been fine sense then.
