P0106 HUMMER Description
The Manifold Absolute Pressure (MAP) sensor provides instantaneous manifold pressure information to the engine’s Engine Control Module (ECM). The data is used to calculate air density and determine the engine’s air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow (MAF) sensor to detect the intake airflow.
