HI there,

This code is for the heater circuit. If you don't replace the O2 sensor it will simply take a little longer for the car to go into closed loop. This is the condition the car is in when the temp is up and the heater circuit on the O2 sensor is there to get it there faster. You will not hurt a single thing driving the car with this problem.
