Help!

Ok, I got my check engine light, well, checked... I got code #P0136, chekced that out on the net... The description was 02 Circuit (Bank 1, Sensor 2). It also told me to chekc out codes P2270, and P2271. I did that, and P2270 said 02 Sensor Signal Stuck Lean - Bank 1, Sensor 2. P2271 said 02 Sensor Signal Stuck Rich - Bank 1, Sensor 2. Basically, I want to know what this means and how to fix it! Please, help me!

RE: Help!

First do you have any exhaust leaks? Exhaust leaks can cause o2 codes. Before dropping money in a sensor I would have it diagnosed by a technician. Other problems can throw o2 sensor codes.
