    Mini One 2002 1600 16 valve W10 B16A Archived Message

    I have this 2002 Mini One that has the MIL on & displays LOS characteristics on the road. It revs nicely in the workshop. It has had some recent accident damage repair & was presented to me with the cooling fan unplugged as it runs constantly.

    The first scan revealed the following codes....

    1484 Electric fan, relay 2 - input low

    0533 A/C system, refrigerant-pressure sensor - input high

    1570 Control unit, sensor supply A - output low

    1222 Pedal-travel sensor 2 - input low

    1692 Electronic throttle monitoring, level 2/3, engine throttle and injection deactivation "A"

    1693 Electronic throttle monitoring, level 2/3, engine throttle and injection deactivation "B"

    0222 Throttle/accelerator-pedal position, sensor/switch 2 - input low

    0123 Throttle/accelerator-pedal position, sensor/switch 1 - input high

    The codes will clear & stay clear for a minute, but then this code returns... (shortly followed by the other codes)

    1570 Control unit, sensor supply A - output low

    Autodata takes me down a path with this code & that is to test the feeds & earths to the PCM & they are all confirmed. I have also scoped the relevant pedal & throttle body connections & it all looks good to me. I have checked for continuity & short circuits in the harness.


    I am begining to think that the ECU is faulty.

    any help welcome
