Default need help code p1170, p1173

i am stumped, i have a 01 discovery 2 with about 140,000 miles. i am showing codes p1170, and p1173. I have recently changed all four o2 sensors with brand new direct fit denso and have no idea were to go. The codes are manufacturer codes and it is very hard to find any info on what it may be. thanks
