1) which sensor is that (right passenger side, rear/post converter?)
2)can i just replace that single o2 sensor?
3)is this the right part bosch http://www.amazon.com/Bosch-13782-Ox...pr_product_top
4)can i use a replacement part/brand or stay with the bosch?
5)where is the sensor located on car if I want to do it myself? accessible from engine area or is it underneath somewhere?
6)could there be another issue or with those codes...will replacing that sensor clear it up?

PM me

your post cat o2 sensor is bad bank 1 is passenger side.
Bank 2 is drivers side.
bank 1 sensor 2 means that the pass side post cat sensor is going.
They are 100000mile units so you should replace all 4.
Dealer over 200 a unit.
www.autohausaz.com about $100
me $210 for all 4 with instructions.
you can get to the front ones via the hood
The post cats via a car ramp or floor jack and jack stands.
Your power will return along with up to a 15% INCREASE IN MPG.
WAITING ON O2 SENSORS will decrease the life of your cats as well as your mpg and performance.
You need 4 2 pre and 2 post. I don't know about those amazon folks at times 3?????
Them $310 for 4

Should the O2 sensors just be replaced at a given mileage or do you wait for problems or codes? 2002 E320 96K miles

Thanks. Didn't know if they were like spark plugs that you had to replace at certain intervals. I need to buy a code reader.
