To test a O2 sensor you will need a Digital Volt Ohm Meter, not the analog type with the needle.

You will want to check a voltage swing between .01 and 1.0volt ( I think the higeher voltage means rich, or vie versa) with the car running.

The only problem with this test, is it does not tell you if the O2 sensor is LAZY. A lazy O2 is as bad as a none working O2. I think the sapling rate is something like 15 times per second. Not sure what the computer is requsting or looking for though.

Good Luck.
