Check engine light - 4 codes
 

The check engine light came on. I took it to Advance Auto store and borrowed the code reader. The following codes are:
- B1317 battery high volt
- C1288 unknown code ( I did some research on the internet, and this is what I found. C1288 - Faulty Pressure Sensor for brake)
- P0171 oxygen sensor bank 1
- P0172 oxygen sensor bank 2

It just seems werid that all four codes popped up at the same time. So, I thought maybe something else is wrong and the PCM misinterpret the real problem.

Any thoughts?

Thanks
