Engine Codes: P0031, P0142, P1148 received after preforming self test. Asked my regular (non Nissan) mechanic about O2 sensor issues, and was told it may be my "upstream" sensor causing two codes to come up. Could that be true? Also, P1148 relates to Air/Fuel sensor problems. Versa has now started to die as I try to reverse out of park. I'm wondering if there may be some sort of defect out there that I am unaware of? Considering there's under 42,000 miles on my vehicle, these issues just seem to be a lot at one time. . . Any thoughts, imput, or ideas would be greatly appreciated!

I have been searching for all possible solutions to my codes: P0031, P0142, and P1148 for my Nissan Versa. I've noticed that there are many different meanings to these codes, depending on the vehicle"s make/model. Anyway, since I was told it was a bad upstream O2 sensor, I have also been notified that it could be a bad o2 bank 1 sensor 3. With all of the information I have been finding online, it doesn't seem like both the front and rear sensors should go out with only 42,000 miles on the vehicle. Also, my last code: P1148 lists the Air/Fuel sensor. Is this yet another bad sensor? If so, what in the world is wrong with my car? There's no logical reason for 3 sensors to go out at once on such a new vehicle. . . Please help!

Really?? Thank you SO much for this information! I will call Nissan right away, and talk to them about this issue. Will they still help even if I am not the original owner? Cost wouldn't normally be such a huge deal, but being a single mom doesn't leave me with hundreds in exra cash just lying around. Ha! Plus, it seemsmy tires are already shot as well, which is surprising considering it's under 42,000. Anyway, that's a $400 replacement on it's own. Ugh. . . I'll repost what I find out after I take it in to Nissan. Really?? Thank you SO much for this information! I will call Nissan right away, and talk to them about this issue.
