I need to replace it. I hate having my CHECK ENGINE light being on! Do I need any special tools? Can I do it by myself? Any and ALL help would be greatly appreciated. The diagnostic at AutoZone gave me a code of PO155. Thanks!

Someone, please help....

Hey Kino, sometimes those sensors are a pain to get out but not special tools are needed. As far as resetting the code I think you need to pull the fuse from the ecu. It would really help if you know someone with a compressor and air tools. Good luck, that's all I have.

Thanks, 7Cain. No one can tell me where it is exactly located and how to do it?

I've only done this kind of work on a Tiburon so my knowledge is limited. Try doing a search here on the forums for O2 sensors, good luck.

Thanks, 7Cain! I know someone has done this with all these 1st Gens on here! Please Help me locate this thing!

I really am tired of my check engine light being on. No one has changed their 02 sensor on their 1st Gen?? Please HELP, again!
