    P1128 Check Engine Light

    in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)

    Posted

    Today I also zeroed the CEL light with an AutoZone OBDII. The code reading was P1128 which, according to AutoZone computers, means "Upstream Heated O2 Sensors Swapped"....whatever that means :soapbox:

    I had the CEL light come on a week ago, after I purchased my 2K Carrera, and was told by a specialist that the O2 sensor on the cat input was bad so he replaced it at the tune of $385, only for the light to come back on after a couple of hundred miles worth of driving. I am new to this car so I can't offer any advice, just my own symptoms to add to your list.

    BTW, I am glad to be part of your group and look forward to contributing if/when I get more knowledgeable on 996s.

    Thanks,
