2009 Chevy Aveo5 LT HO2S Sensor 2 - Oxygen Sensor Location

So I have been searching and searching to find the O2 sensor 2. I found the sensor under the hook, but unable to find the sensor under the car. It should be past the catalytic convertor, but I am seeing nothing. If someone could give me a better location, or even a picture, that would be most helpful.

I have a weird feeling that the sensor may just be missing...

My error codes are as follows: P0036, P0137, P0138, P0140, P0141, and P2270 - All come back to HO2S Sensor 2.

Chrispy, The sensor you can see from under the hood is attached to the exhaust manifold. The one you can't find should be on the catalytic convertor. Have you looked near the second convertor further away from the engine?
