.5V refers to 02 sensor, pulse ratio refers to the modulating valve ... you appeared to lump them as one ...
connected, the lambda sys controls by oscillating the pulse ratio of the mod-valve, rich lean, based on rich lean reads off o2 sensor. so you need an analog meter to properly see o2 voltage swing, and mod valve swings, since the time constant and aliasing of a digital vom may be misleading.
bentley has proper specs for mod valve, about 40 to 50% as I recall at idle.
