Need help with O2 Sensor codes

I replaced my bank 2 sensor 1 after getting a code PO153 and it has been fine for about 2 weeks and approx 3 tanks of gas, last night I got a PO152 which is for high voltage on the same sensor. I got the O2 sensor from the dealer is it possible that it was a bad one or should I be looking for something else and if so what?

Could be a short in the wires or the connector. Check that first. If you can't find anything, check the output of the sensor with a multimeter.

The Jeep is an 06 and only has 34K on it, I did check all the wiring when I repalced it about 2 weeks ago and everything looked like new. I have a multimeter so how do you check the sensor? And what should the readings be?
