The map baro switch solenoid valve is used to switch the airflow passage based on voltage signals sent by the ecm.
P1105 meaning the manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine s engine control module the data is used to calculate air density and determine the engine s air mass flow rate which in turn determines the required fuel metering for optimum combustion.
This information then determines how much fuel metering is needed for combustion.
