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!

 

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.
