I need to replace the oxygen sensors on my car. I found one of them but it is hard to get out. I can't access it from below the car and it seems impossible to get because it is near the alternator and a bunch of hoses. I don't know where the second one is (I believe there is two). Please post pics if you can. Thanks.

 

The second one should be in the pipe after the catalytic converter.

 

both are accessible from under the hood i did both of mine the passenger side is harder i just used someone with a smaller hand than me and took a little bit of work.
