Hi,
If the sensor is new, chances are it is a wiring issue. By chance, do you have a live data scan tool? If you do, check the voltage signals from the involved O2 sensor and let me know what you are seeing. The code indicates the heated component in the sensor doesn't reach 959F within 45 seconds, so chances are it isn't powering.
Also, if you look below, I attached the diagnostics for this code. Take a look through them and let me know if you are comfortable performing them.

Let me know what you find or if you have other questions.
Take care and Happy New Year.
