OBD Code P1128
My check engine light came on and my buddy read the code as P1128, his manual says it the "O2 sensor", I called the Porsche dealer and they said its a "lean air fault" and will need to bring it in to have them look for the problem and fix it.
Does anyone have a have a list of the Porsche codes, or, do you know where I can get them? Thanks... 99 Boxster |

The codes are listed on RennTech.
I have the OBDII book. The oxygen sensor thinks the car is running lean. |

Did You ever find out what made your OBDII to regester the P1128 code?
My 2000 Boxster's CEL came on and the scanner showed codes P1128 and P1130. This is both O2 sensors. I reset it and about a week later it came on agine showing the same codes. I ran some injector cleaner throught the system, checked for intake leaks using carb cleaner and checked the fuel cap. It was ok for about another week, but the light came on again. Any other ideas?? Thanks fud

I kept getting this on my 98 with 98K. Turned out being the MAF.

I had the dealer do it as I wasn't sure that's what it was. I had a strong feeling it was though, but the wife didn't want me throwing money. I did tell the service guy that I enjoy doing my own work and for now on I may be in for the trouble shooting but then I'd do the work. He said he understood.
