We are working with an 07 Versa S with 140K miles. I have 3 codes P1148, P0031, P0130. I have already replaced the upstream O2 sensor with a with a Denso 234-9070. I have unplugged the negative battery terminal for hours to reset the light and it comes back on instantly. I have also checked the fuse for the O2 sensor and it looks fine. I am starting to think it may be a wiring issue and would like to check the grounds and the voltage on the connector. Can anyone help me find what would be a correct reading from each of the 4 pins and maybe a good wire diagram of the system I am working with. I am also open to any and all suggestions on a solution to these 3 three codes. I have done some searching and found plenty of people with the same 3 codes but no one ever seems to solve it or they never update the thread with the solution they found.
