    Hi everyone,

    Chasing a fault with codes P0150 and P1112 on the left bank, swapped MAF's left to right and front O2's over too, cleared codes but the faults return on the left bank again,

    Is there something like a fuse or earth common to the left bank air flow and front O2 ?

    Can i swap the motec's left to right to see if the fault follows ?

    Any help appreciated
    Thanks
    Damien

    Use live data on your diag tool and see what values you are getting for O2 voltage and temp from MAF

    Most likely wire harness connector .. I don't have wiring diagram for the 360 in front of me maybe @Qavion can assist

    There is a common fuse, but I think there would be more messages if the fuse was blown.

    Depending on your year/country, the fuse is #60 or #58. See blue arrow.

    The fuse is behind the driver (LHS) middle fuseblock (top right blue fuse, looking towards the rear of the car).

    In the diagram, fuse power is supplied to a big splice "S148T" which has lots of violet coloured wires ("Z" colour code). The fuse is provided with power from the LH Master Motronic relay.

    Wow, Thanks so much for the quick response, really needed the wiring diagrams, live data was nonsense, power was ok to the sensors (thanks for the above diagram) but signal was not, looked back to the ECU and found 3 bent pins, straightened those and carefully refitted, tests ok !

    Thanks so much for the help :)
