This is because OBD II standards require O2 sensor PID voltage to be displayed in a range between zero and 1 volt. Newer vehicles will have accurate air fuel sensor voltages. * In generic OBD II what you often see is a percentage of true voltage.
Measuring voltage. To run a test to measure voltage, you connect the red multimeter lead to the positive side of the battery or circuit that you're testing and the black lead to the negative or ground side and set the dial to the voltage range you expect. Consider checking the voltage at the contacts of a battery pack.
