Where is it
someone in another post said to clean it idk im just giving it a shot. i said all becuase i did not know if there were more then one on mine because my jeep had two and my friends lexus has like 5
I suppose you can clean the o2 sensor's protective housing, but don't use any chemicals to clean it. Really though, if it's just carbon deposits on it, you can just wipe them off with a paper towel...as long as they're not caked on. Don't use a cleaner of any kind on them though bro. Don't forget to put anti-seize on the threads too or you will have the hardest time trying to get them off later.
BTW, the one by the cat is only for the EGR system. It tells the computer if the cat is working fine or if it's not.
The one on the o2 housing is the one that matters to the motor. So, if you're car is running overly rich or lean, that's the one to check.
