Where is the oxygen sensors located please?

Hi, as part of my experimentation with the engine I need to locate the oxygen sensor(s).
Can anyone provide a photo for me and tell me how many of them a 1997 (first CRV Honda made) has please.

Thank you very much.

Parts #22 and #23 are the sensors you are referring to. Be advised, however, that the "upstream" sensor is not an O2 sensor in the traditional sense, it is an A/F sensor. Your rear oxygen sensor is a true old-style heated oxygen sensor. :)
