Where Is Bank 2, Sensor 1 (o2 Sensor On A 1996 Gs)

[kino1161]

I need to replace it. I hate having my CHECK ENGINE light being on! Do I need any special tools? Can I do it by myself? Where in the engine is it located? Any and ALL help would be greatly appreciated. The diagnostic at AutoZone gave me a code of PO155. Thanks!

This is prob. not a good idea if you havent done one b4.As far as special tools a o2 socket is very helpful but it can be done without.These can be seized up and very hard to remove and you DO NOT want to break it off.As far as where it is, it is very hard to find as it is toward the front of the vehicle buried up near the motor.If you do decide to replace it yourself try not to use cheap Bosch junk.Good luck
