Code P0105 Nissan Description

The P0105 diagnostic trouble code for Nissan vehicles indicates a malfunction in the Manifold Absolute Pressure (MAP) sensor circuit. The MAP sensor is a crucial component of the engine management system, as it measures the intake manifold pressure and provides this information to the engine control module (ECM). This data is essential for the ECM to calculate the correct air-fuel mixture for optimal engine performance and efficiency.
