Where is the O2 sensor located on an 2001 Oldsmoblie Aurora?

Question

Where is the O2 sensor located and how difficult is it to replace? is it something that I can do myself?

Answer 1

It will be by your manifold and before the cat converter but you probably have more then just one on that yr vehicle.

Sometimes they can be a real pain especially the ones upfront so best to take it to a reliable shop and pay the few bucks to get it installed.

Some shops might do the labour for 20 bucks a piece or no more then 40 bucks tops.

Hope that helps and best of luck.By the way try not to use aftermarket o2 sensors and always try to make sure that it is the o2 sensor before changing them.

Answer 2

O2 sensor is always located on the exhaust manifold / header pipes.

It is something you can do.  You just need a O2 sensor tool (and some liquid wrench).  Sometimes you can just use box wrench (if you are lucky).

Good Luck...
