Hey there, just got a 2011 aveo and now the check engine light came on. Looks like it's the o2 sensor. Trying to figure where there are, think there's 2 of them, so I can. Heck which one is bad. Pictures would help a lot. I think I can see the front one, but it's surrounded by a piece of metal that will make difficult to remove the sensor ( I can disconnect the plug easliy).
any help would be appreciated, thank you. And again, pictures of the locations will help me even more. Thanks again
