I was driving along tonight and the SES light came on. When I scanned it, it gave me a P1131 or P1130 I can't remeber (P1131 I'm pretty sure), but it said the problem was a factory problem-air/fuel metering. Does anyone know what in the world this is, or even what I'm talking about? Thanks for any help.

Which O2? I got a code about a week ago that said that my O2 sensor circuit Bank 1 sensor 1 had low voltage. I would assume that this would be the one to replace? I haven't had that code pop up any since then. I was just hoping that it was a false code. Thanks for your input.

From what i was told a while back. The low voltage code is meaning that it scences high o2 levels. Basicly meaning you have a leak in your header/manifold. Or in severe cases it means your fuel pump is going out. (but i doubt that). Reason why i know this is because i have a low voltage code as well. And asked this a few weeks back.

 

Maybe it was P1133-insufficent switching bank 1 sensor 1. If you had low voltage indicated before, I would suspect the sensor.

 

Thanks for the help. I will wait until it pops up again and try not to be so impatient and delete the code right away. I had my O2 bank 1 sensor 2 go out about a month ago and I replaced it. Maybe its about time for the first one to go too? Is that normal...I only have 56K on the car?
