Could use some help with reading this OBD scan

I live up in Boston and we had a -5 degree day over the weekend

Monday morning the check engine light popped up, no signs of anything being wrong.

Had the check engine codes scanned and wanted to see if any members could help me with what is wrong, I think its the 02 sensor ?

Also if it is safe to drive on this until next week to drop it off to have fixed.

thanks guys

P.S.
please come back and tell us what you find and your eventual solution.

Most of the sensors that are indicated by your scan get power from the same source (Z7/36, circuit 87) ... I didn't see which fuse that is.

I had a similar failure on my SL55 , replaced the fuse and it never came back (probably will someday).

You probably won't get stuck driving it as is ... but I would not go too far.

Cheers,
Chris
