So for those who haven't heard my story, my O2 sensor went bad awhile back and i replaced it.
However, i'm still getting a CEL stating that i'm getting a low voltage on my O2. Anyone else have/had this issue? I double checked that i had it was plugged in properly and that nothing was loose or bent.

there are 2 o2's, pre cat and pos, if you want to stop by my class on friday, i can hook up a solus to your car and see if the problem is really the O2's.

anyone else have any suggestions or experience with this similar issue?
i just reseated my O2 and it's still giving me a CEL.
i still don't understand why it worked fine the first time and now it's giving me a low voltage?

did you put anything on the thread? it uses the thread as ground, any thing that goes on the thread can be a resistance to the circuit...

i thought that was just a corrosive protectant?

Did you buy a direct replacement one ar a universal one where you splice? Also, do you have access to a scanner and can get the voltage output readings for the o2 sensors?

Did you run over something and it hit the O2 sensor?
