Code P1103 2002 Nissan Sentra Description

The P1103 code on a 2002 Nissan Sentra indicates a problem with the MAP (Manifold Absolute Pressure) sensor reporting a high voltage to the Engine Control Module (ECM). The MAP sensor is responsible for measuring the intake manifold pressure, which helps the ECM calculate the correct air-fuel mixture for efficient combustion. When the MAP sensor reports a high voltage, it means that the pressure in the intake manifold is higher than expected, potentially leading to an incorrect air-fuel mixture being delivered to the engine.
