If it fluctuates, there is likely a problem with the oxygen sensor.

If the readings stay constant the oxygen sensor is operating correctly. It should be between 100mV and 900mV. It should fall within the range of 100mV - 900mV.

If you own a multimeter make sure you warm the car before conducting tests. The voltage on your digital multimeter can rapidly fluctuate between 0.01 volt and 1.01 volt when it is warm. The oxygen sensor might be malfunctioning if the readings do not fall within this range.
