Drivers rear o'2, should be located in the second cat. or just infront or behind it.

 

If the O'2 sensor is behind the cat. The cat may be bad. It might be wise to make some phone calls to Muffler Shops in your area, to see who gets OBD2 cat's rebuilt. They also should be happy to check the status of the cat in question.

 

Thanks! will check it out.

 

Has anyone been under the car working on something lately?

I know...stupid question. I had a similar code with the old 89 ranger I had.

Somone (who shall remain nameless ) knocked the wires off the O2 sensors while under there.

 

The location is in the left exhaust pipe after the rear of the cat.
