Hello, I have the SUV lsiuted above with an EFI OHV 4.0 v6 engine. I had a p0136 code pop up on me so I plugged up my scanner and it read 02 sensor malfunction bank system 2. I also did a ready test and took a shot of both results can anyone help me decipher this? What does these two scans mean? And what is my next steps on fixing this and get my check engine light off?

Hello, I am Danny.

It looks like your heated Oxygen Sensor is failing. That code is for Bank 1 Sensor 2 malfunction.The sensor is mounted in the exhaust pipe on the right side after the catalytic converter. Sensors are subject to normal wear and tear ans sometimes due for replacement during normal use. I have attached a few tutorials for you to view. Hope this helps and thanks for using 2CarPros.
