Replaced HO2S, reset ecu, still throwing CEL 1

WTF...

so I got my CEL working, it was throwing a code 1 for my heated oxygen sensor... replaced it today. Hooked everything back up, reset the ecu, started the car... CEL still on? wtf!?
reconnect the service connector and check the code and its still a code 1... for the HO2S...
WTF, need help here guys...

I also noticed something fishy theres a sensor plugged into the right hand side of my intake manifold/throttle body, that has the wires cut off... this might have something to do with the ecu bitching...

any clues!?

I hope to god that you figured this out by now, but if you didn't or anyone else ever stumples upon this thread, it is most likely your sensor on the right side of the manifold, IAB i think. Fix it and reconnect it. This fixed my error. It is hard to troubleshoot since it gives an o2 error for some reason...
