Engine light came on, and showed up as the Oxygen Sensor -- NO CHANGE IN VOLTAGE/OPEN CIRCUIT.

Whats this mean then?? and where's the oxygen sensor??

Cheers, Corb.

It is lambda sensor, before the cat. If you don't have problems with engine eg. no overfueling, no idle problems etc. , you can ignore it. I suppose that ECU light is not constantly ON?

Just be carefull to watch for things I told you before. I had code 13 staying for max 1 min a couple of times and 1 year later no problems, and no stored ECU faults. One thing you could do and it doesn't hurt, is to clean contacts after oxygen sensor (3-pin connector)
