I am still not sure which oxygen sensor you replaced? I attached an image to show you the correct location of the sensor. Bank 1 sensor 2 is the one on the catalytic converter. Depending on your emissions rating which you will find under the hood on the label the pin configurations are different.
On pins number three and four measure the resistance for the heater circuit. If it is not within spec replace the sensor. And as stated earlier depends on your emissions rating, pins number three or number number will be the power supply. With the key on engine off you should see battery voltage to one of those pins. Let us know how your test goes and if you had to replace the oxygen sensor on the catalytic converter.
