Codes p1167 p0159

Hey guys I have an 2003 fx 35 12500 mi. I tried searching the forum for the codes I have with no luck.my check engine light came on I had it scanned at the local parts store and got two codes p1167 and p0159 .the car doesn't seem to drive any differently the check light goes off for a couple of days then comes baking on for a while then goes back off etc. Along with the codes I did receive a list of possible causes if anyone has any trouble shooting ideas to narrow this down and figure out the cause I would appreciate it thanks.

Ok thanks for the info.so what I'm taking from that is to replace the rear o2 sensor for bank 2 .anyone have any experience with that as far as location of the sensor. And if it's a real pain or not thanks
