Checked the code and the reader came back with a P0160 - 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2).

Can someone guide me to Bank 2 Sensor 2. I am assuming that the Bank 2 oxygen sensor is on the back side exhaust and sensor 2 is further away from the engine.

 

I'll double check tommorrow at autozone but bank two should be the back side of the engine and sensor two is after the cat.

 

I already found out. I too thought that bank 2 would be the firewall side but it isn't. Bank 2 is nearest the radiator and bank 1 is the firewall side.
