Hey how are you ,I will try to help you with this issue

DTC P0031 , you have to start here and repair or replace and clear fault codes and test drive and see if other codes come back, the other could be collateral fault codes caused by the p0031.

now click on link to see the Trouble shoot steps for dtc P0031 there is several steps here , i also included the rest of the troubleshoot for the rest of the fault code u sent .

most likely you need an a/f ratio sensor ,but testing is needed as you can see from the troubleshoot steps it could be several other things so run the test so you are not throwing parts at it and guessing and be accurate

You are very welcome :)

I was in trouble with an electrical issue with my brand new Nissan. I frantically went online trying to find help and luckily I found your site. I reached a NISSAN tech named RIP. He was absolutely tremendous and helped me work through the issue. What a pro!
