A/F ratio sensors are being discussed. Technician A says the output voltage of these sensors is much higher than a conventional O₂S (oxygen sensor). Technician B say when the output of an A/F ratio sensor is looked at with an OBD-II generic scan tool, the voltage range will appear the same as a conventional O2S sensor, 0 to 1 volt. Who is correct?
