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.
The 3-wire meter I have has a red wire for its + power, black wire for its - power, and white wire for its reference voltage. Connect the red wire to the power supply +, connect the black wire to power supply - and connect the reference to buck converter + output. * This will work as long as your meter can take the power supply's voltage.
