    Fault Code 42 -speed sensor.
    Could be damaged speed sensor, faulty electric connections or wiring, or faulty ECU.
    Turn front wheel in direction of normal rotation and check pulses are generated and displayed. 0 to 999. Will go back to zero once 999 is reached.
    This is taken from the Haynes manual and I have no direct experience of this fault.
