    I have a 94 850 non-turbo. I'm getting the following codes and need help
    interpreting them:

    A6 Ignition: 1-1-1 1-2-2 and 2-3-1 (I thought 1-1-1
    meant OK, but then the other 2 codes came up)
    B2 Cruise Control: 1-2-2

    Any help would be appreciated.

    Thanks,

    Chuck

  2. Asuming you have a Fenix 5.2 controlled engine:

    A6 1-2-2 : Faulty air temp. signal
    A6 2-3-1: long term fuel fuel trim part load, lower limit.
    Possible source:
    -High fuel pressure.
    -Leaking injector.
    -Dirty engine oil.
    -Oil level too high.
    -Leaking EVAP valve.
    -Faulty sensor signals.


    The B2 1-2-2
    is normal if vehicle speed has not exceeded 35 km/h after ignition has been
    switched on.
