How
many miles on the car?At 100k the o2 sensors are regular maint. replacement items and yours appear to be failing.Both are post cat sensors(after the cats)
you really need to get it on a scope that shows function of the sensors and tests operation of the cats.To rule out possible cat failure.
Have you been driving around ignoring a check engine light?
Have you noticed a big drop in fuel mileage?
Did you know that for $39 you can get a good obd2 scanner from
http://www.harborfreight.com/
Item 94169 if you have a store near you they will meet the internet price if you take in a print of the web ad.
Then you can read your own codes in the future and clear them when you have done the repair.Also reads emission readiness status so you know when you are good to go at the smog station.

autohausaz.com usually carries the sensors,ask them for a quote.They ship free over 50 bucks.

The real problem I see is that you have no light.If you bought the car in the last year and the po removed the bulb something was wrong and they knew it.You are now paying the price.Did they run the tests or just hooked it up and said unable to run tests due the the presence of obd2 codes?
Something is causing those post cat sensors to be out of flat line and like the member above said it could be the pre cat sensors it could also be other problems upstream.Who knows what damage has been done operating out of range,but if something was not on the up and up from the po I would get it on a scope and find out what was going on before throwing parts at it.

what year C43?
Your mbtech has a good price for the two precat sensors I would get it on a indies diagnostic machine first to really find out if something more serious is going on.

Not
meaning to scare you since most of those cel's have simple solutions,some that don't even cost much
However if someone intentionally shut down the system to hide the cel light you need to find out what is wrong so it can't do more harm.
