High voltage reading from o2 sensor

I replaced my o2 sensor with a new denso sensor after finding a abnormal high reading from the o2 sensor. The problem seemed to be fixed then a few days later i looked at the o2 readings and i was reading high voltages (3.0-3.8). Any insight would be much appreciated.

loose connection within the harness, or prehaps the pin in the plug has pushed out,

Im going to check the connections at school this evening. Does anyone else have any ideas what would make a newly replaced o2 sensor ready 3.87 or so at idle.
