Answer
Go to a parts house, and get them to connect their scan tool. You can read them while they work.

If you seem to get an oxygen sensor reading, it doesn't actually mean the sensor is bad. it could be giving a completely accurate reading, and the exhaust is either rich or lean. The oxygen sensor may not need replaced. You may just need to find the cause of the reading it is getting.
