Where are the O2 Sensors located?

Hello, are you getting certain codes for either oxygen sensor? There are 2 in this vehicle. I will post diagrams for both. But the front oxygen sensor is a pretty advanced sensor, it has a built-in temperature sensor along with a heater circuit which all oxygen sensors have. So, if you are getting a check engine light and certain code, it would be good to look up the code setting criteria for them. And is this a 2.0-liter engine?
The rear Oxygen sensor needs a specific socket to remove the sensor. The part number is on the 4th diagram.
There is also a Technical Service Bulletin about other causes of Oxygen sensor codes (5th diagram).
