Have you cleared codes?
THE LIGHT WILL NOT GO OUT UNTILL THE PROBLEM IS FIXED AND YOU CLEAR CODES.

Codes do not say repace sensors.

The code is for a heater circuit on bank one sensor 2.

Are you sure you are on the right sensor?
Wher was the one you replaced?
Check for heater circuit voltage and ground to that sensor.
Is fuse to it good?
Is wiring and plug in good?
