QUESTION: Thanks , i dont know if you got that last message but i was sayin that someone told me i should have disconnected the battery before changing that sensor, and that could be the reason i'm still getting that error,could that be true?


Answer
no because its a ckt that is checked by the PCM  if u had the key out of the ign then it would not have voltage on it. If u already have done the repair  run the car for 10 min each then cycles the key off then restart it back up  if  do this 3 times and the 4th key cycles the light goes out then u have fixed the prob with the o2 replacement. This processors is what the computer does is checks the same area to which the light was turned on in the first place  3 times and it turns out the light.
