Check Engine light on and Code 153..... Rear O2 sensor replace? 850 1995

First time today I got this Check Engine light on and the Code 153 in A2... I think I will go and replace the O2 sensors (yes both.. I guess)
I would like to know how difficult that could be and where can I get those O2 sensor (not expensive)? also If I need a special tool as I see offer in Ebay...
Can I still drive my car? I reset the code now is off.... maybe I will drive my car tomorrow to see if the light go on again....

Any input will be really appreciate.....

    No need to replace both, just the rear. I'd only use an OEM Volvo O2 sensor. There is no special tool required, just a 7/8" combo wrench and a 12mm socket to remove the rear plate bolts.

      i have 850 1996 and i had pretty much similar problem codes were:
      "P0133 O2 SENSOR CIRCUIT SLOW RESPONSE (BANK1 SENSOR1)" ,so
      my mechanic assumed that the problem was in the nearest sensor to the engine -logically right ,BUT, wrong!!! we lifted car up and checked sensors (2 of them) front looked just like new(closer to the engine) but the rear one on the exost pipe looked really old ,before that we checked i-net for new sensors.cheapest we could find is 150$ so not really cheap.so we pulled rear old one out and JUST CLEANED THAT WITH WD40 (RUST REMOVER)-the only thing we had by the hand that time with hope it will help -and miricle IT HELPED!!!
      As i can see your error bit different but it still can work just check it visually if its really darken or corrosive,clean that off MAKE SURE YOU ARE NOT USING ANY ANY TYPE OF SANDPAPER OTHERWISE YOU SCREWED!!! just tender cloth with any type of cleaner : wd40, gasoline ,spirit,aceton,so on.
      good luck any questions feel free to contact me :woorst@hotmail.com
