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.
If you own or can borrow a multimeter, place the negative and positive on top of the appropriate terminals while running the vehicle. Adjust the meter to read DC voltage and your screen should read between 13.8-15.5 volts.
