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.
1 You will see a reading on the screen - on a good electric fence line this should be in excess of 6,000 volts.  If the voltage is just slightly below normal - say 5,000 volts - then you probably have a small fault caused by light vegetation, for instance.
