Defective Oxygen Sensor - Bank 2 sensor 2
I turn on the truck, it starts to vibrate and sometimes I smell a fuel odor.
Would these codes cause the fuel odor to come out?
I know where the MAF sensor is on the truck But Where are these oxygen sensors located?

Keep the points I don't do this for "points".
The code did not say the O2 sensor were bad, it said the readings were out of spec. The mass air flow could very well be the reason for all the codes, and it is most like the reason for the gas smell. It is giving the wrong information to the computer which I'm betting is dumping in to much fuel. They make a cleaner for it but I don't have much faith in it. There is a very small wire in the MAF sensor that could have broken, an ohm meter can tell you that.
