Code P1105 1997 Infiniti I30 Description

The P1105 diagnostic trouble code (DTC) for a 1997 Infiniti I30 refers to an issue with the Manifold Absolute Pressure (MAP)/Barometric Pressure (BARO) Switch Solenoid Valve. The MAP sensor measures the pressure within the intake manifold, while the BARO sensor measures the atmospheric pressure outside the engine. The solenoid valve controls the switching between these sensors. When this code is triggered, it indicates a problem with the operation of the solenoid valve, which can lead to incorrect pressure readings being sent to the engine control module (ECM).
