Code P1106 Buick Description

The P1106 Buick code indicates a problem with the Manifold Absolute Pressure (MAP) sensor circuit, specifically an intermittent high voltage issue. The MAP sensor is a crucial component of the vehicle's engine management system, as it measures the pressure inside the intake manifold and sends this data to the engine control module (ECM). The ECM then uses this information to calculate fuel delivery and ignition timing, optimizing engine performance and fuel efficiency.
