I was on my way from school and I noticed my CEL was on. It went off soon after and came back on after a few minutes, then went off again in under a minute. I was accellerating in 5th gear up a slope when it came on so that kight have something to do with it.
Here are the codes I got.

111 PASS
10
172 Heated oxygen sensor indicates lean condition, right side


What needs to be done?

And my codes for the fan relay circuit fault and fuel pump circuit fault are gone since I changed the CCRM. :D

I will most likely means that your oxygen sensor is bad, i had the same code but on the left side after i got on a flooding , after that the oxygen sensor was making that code , replaced both and no probs since then, i will highly suggest to replace both at the same time , since you will like to have clean readings to the eec on both banks :nice:

Ohh and of couse disconnect battery while you are changing them!
 
I'd check the frequency and amplitude of switching on that particular O2 sensor. 5 minutes with a DMM can save 50 bucks.

Good luck.

Since you're only getting a code for one side, there's a decent chance that it is the O2 itself, or the wiring to the O2.

Oddball question:Do you run a narrowband O2 gauge? Some of them don't have high enough internal resistance and can almost freeze the O2 signal.

If you had two O2 codes, I'd think vac leak, MAF issue, etc. But with only one side, it's likely the O2. I can't stand buying new parts without testing first though.

Good luck Eric.
