I just fixed my EGR issue and then when I went to get the code cleared it came up with two more codes (lucky me)!!

I got a P2271 "O2" sensor signal "stuck rich" bank 1 sensor 2

I also got a P036 "O2" sensor signal Bank 1 Sensor 2 code

So does any one have a picture of the location of this sensor. I was thinking of trying to remove the sensor, clean it with Carb cleaner, and put it back in. Would this work? and how hard is it to get to this?

Am I thinking right or is there some other thing I should consider when trying to fix this?

There isn't a P036 "O2" sensor signal Bank 1 Sensor 2 code it that a typo?

There are 23 Oxygen (Lambda) Sensor 2, Bank 1 codes.

EOBD II Error Code: P2271

Fault Location:
Oxygen (Lambda) Sensor 2, Bank 1/Heated Oxygen Sensor 2 (G39), Bank 1 - Signal Stuck Rich

Possible Cause:
Oxygen (Lambda) sensor.
Heated Oxygen Sensor (G39).
Fuel pressure.
Air intake restricted.
