Moaning Help Please Error codes P0170 and P1172

I fitted a new lambda probe last week and I just went out to check the fault codes and these two are still standing, even after clearing the codes they still appear.
Can anybody help in determining the cause of these faults, this is what they read as:

P0170 Lambda control above upper limit
P0170 Lambda control below lower limit
P1172 Lambda adaptat. 2 (additive) above upper limit
P1172 Lambda adaptat. 2 (additive) below lower limit

Surely it cant be the lambda after a week can it???
