Hi there,

Without the specific code it's difficult to answer your question. I would say that first and foremost, just because the O2 sensor "looks" new, doesn't mean it is. If the code is for the heater circuit on the sensor then it's usually the sensor causing the problem. If it's some other code that is only associated with the sensor, then it's generally not the sensor causing the problem, but something else and the senor is reporting it.
