    Limp mode,

    Hey guys/girls

    Im new to this forum, and have been looking threw it most the day,
    I have a 2007 Holden Astra SRI 2.2 with 205k on the clock.
    It went into the local mechanics the other day, as it went into limp mode, with it stuffing up a coil pack,
    I had the coil pack changed out for a new one, along with new spark plugs,

    The car is still going into limp mode on start up,
    I was told its throwing code
    U2103
    P0460
    and that the mechanic I gave the car to does not have access in his scan tool to look into them further.
    I am unsure of what causes both codes, and unsure of how to fix it,

    I am aware P0460 is in regards to fuel sensor,

    Any help greatly appreciated,

    Was the coilpack genuine or aftermarket?

    Aftermarket coilpacks are crap and are known to prematurely fail. Start with a genuine unit and see if that fixes anything

    U2103 is no canbus signal.
    That will be throwing it into limp mode.
    Where are you located?

    Sorry I can't help out. I'm in Melbourne. Canbus signal means there is a sensor not receiving or sending a voltage reading
