O2 Sensor

[pinetopfirefighter]

Hi......

My wife has a 2005 Aveo and the engine light is on. Codes say that it is the O2 sensor(s). I would like to change these out myself, but I am not sure which ones are the sensors. Just such a small area and lots of crap in there. Can anyone help out?

Thanks, Matt

Hello, Guys

do you know what is the OEM part number of this oxygen sensor you show in the picture?
