you have 3 sensors 2 on the engine are the same the one after is slightly different.

You may have had one changed before and they may have cut and spliced a new harness on.

yeah I did take out the one after the engine, so how do I know which sensor is bad in the first place?

Most times they are not bad, but slow. You can test (while on car) on fast they can change volts. Don't feel bad in 4 years I have yet to find a rad car (from the dealer) that fits..

If the connector plug is different do not splice wires to install. Cars that meet CA specs do not use O2 sensors they use Air/fuel ratio sensors. They are located in same places and are same size but are very different .... do not interchange. Some after market sensors do not come with connectors and must be spliced .... I would not install sensor without connector.
