How to replace an O2 sensor in a 95 Protege 1.5l?

[Little Jerry]

Does anyone know where I can get some step by step instructions in replacing a O2 sensor? I found some for a civic, and I guess the process is the same, but I dont even know where it is on the Protege.

I would pick up a decent protege service manual and check it out for the proper procedure. I've done most (if not all) of the service work on my pro by just following the manual. Of course, you'll want to get a decent ratchet and o2 sensor socket to make the changeout.

Which sensor is it, the manifold or downpipe?
