Code P1103 Nissan Description
The P1103 code for Nissan vehicles indicates an issue with the MAP (Manifold Absolute Pressure) sensor, specifically high voltage readings. The MAP sensor plays a crucial role in the engine's operation by measuring the amount of air entering the intake manifold. This information is used by the engine control module (ECM) to determine the correct air-fuel mixture for combustion. When the MAP sensor detects high voltage, it suggests that there is an abnormal amount of pressure in the intake manifold, which can lead to a variety of performance issues.
