How can you tell which O2 sensor is bad?

To perform the actual test,

start the car again and check the voltmeter's voltage readings

. The o2 sensor's voltage should fluctuate within the 100mV – 900mV (0.10V to 0.90V) range. If it is within this range, the o2 sensor is operating normally and you can stop testing.
