2003 Camry oxygen sensor

Hello,
I have 2003 Camry, V4 with about 125K miles. I was being an idiot earlier when jumping another car and put the wrong terminal on the other battery causing it to spark and my battery to die. Long story short, I got my car's battery jumped and took it to autozone. They said my battery was fine, but said that either my oxygen sensor or A/F ratio sensor circuit low- bank 1 sensor 1 (P2238). Furthermore, they gave me 4 probable causes: 1. open or short circuit condition 2. poor electrical connection 3. Failed A/F sensor 4. Fuel pressure, vacuum leak, MAF sensor fault.
The car does not run as smoothly as it did before. Thanks for your help!

You know, that's the problem with the people in these parts stores trying to present themselves as technicians. That is not even close to what that code means. That code is for a problem with the Throttle/pedal position sensor d/e voltage correlation. This has to do with the "drive by wire" system and one of it's components. This is not something that you are going to be able to deal with. It's going to require a factory scan tool and extensive diagnostics to solve the problem.

Thanks for the response. I googled this particular code and they all seem to be consistent with that they told me at autozone. Not to say that I think you're wrong, but where did you look up the code?

I stand corrected on that one. I was looking at a P2138 instead of P2238.
That is a low voltage code for the upstream 0/2 sensor. It could be many different things from a lean mixture to a bad heater circuit for the sensor. it needs a lot more testing first.
