When O2 sensors go bad... or do they?
About 2000 miles ago, I had a CEL. Checked the codes, I had a rear heated O2 sensor code. I cleared the code, bought an O2 sensor, and haven't had time to install it. I haven't noticed any problems since the CEL, and my gas mileage is fine. So the other day, I checked the codes again to see if there was a KS ghost code or anything similar, and I got 0505. So, the question is: is it possible that the O2 sensor is OK, and it was just having a bad day when it tripped the CEL, or once I cleared the code, did it stay clear for good? I would think that if the O2 sensor is bad, it would trigger the CEL again and store the DTC in memory right? What do you fellas think?

I did the same thing and my CEL came back on after I drove for a little while longer so I have to change mine out... We should only use oem ones right? So that is bosch or does it not matter?
