The short answer is No. The current output from a Air/Fuel Ratio sensor is ususally less then 2 milliamps. Although this clamp reads in the milliamp scale, noise at that low of a level will make the waveform unreliable at best.
You would need to purchase a Microamp clamp, such as the AEMC K110, to measure it directly.
If you have another slack in the wire and can wrap it around the jaw 10 times, this would increase the output read from 1mV to 10mV which should be more visibile.
You can also do a voltage drop test aross a 10 ohm fuse or aross the sensor wires if you can get sufficient data on the sesnor.
