I have a check engine light and it was diagnosed as rear oxygen sensor. Under the car, I only see the 2 before the catalytic converter and not one after. The auto parts store says there is one after. Anyone know where it is located?

There are two in front of the cat and 2 behind it right on the pipe. The leads on the rears go into the car so if you are going to an auto parts store, most likely they will sell you a generic Bosch unit which will splice into it.
Hope that helps

Thanks, once I replace the sensor, do I need to disconnect the battery of fuse to reset the engine light?
