    What's the question? Be specific.
    Code P0105 indicates that the computer has detected an open or short in the MAP/BARO circuit. Could be due to a failed MAP sensor or a fault in the wiring or connectors.

    Most likely it is a defective MAP sensor, but make sure that the wiring is not chafed, there is a TSB for the MAP sensor wiring rubbing on an engine bracket and then setting a MAP code.
