Would it be possible that codes P0134 and P0171 are related to a same problem

Question

Even with codes reported, car is going well. Both code have started to be reported almost at the same time ? When erasing codes, it may take few days before they came back. Sometimes it takes week.
Would it be possible that they are related to a same problem ? What is that problem ?
Nissan Altima 2000 - 2.4l : P0134 & P0171.

Answer 1

Yes, the P0134 code is for the front O2 sensor. If the front O2 is failing, it can cause the engine to run lean and give you the P0171. I would replace the front O2 sensor and take it from there.
