GMC Sonoma MAP Sensor is an important sensor that used to measure positive air pressure of intake manifold entering the vehicle engine and convey real-time information to the ECU for the setting of fuel injection calibrate. In fuel injection systems, MAP sensor is employed to calculate density of air together with estimating proper fuel/air mixture that is necessary to burn fuel. Sonoma cars may use the MAP sensor, a mass airflow sensor, or both depending on if it is a forced induction engine. They also include helping in the on-board diagnostics, and in the string testing of the Exhaust Gas Recirculation (EGR) valve. In general, MAP sensor plays a crucial role in fuel control, ignition control, improving the overall driveability of the car and so on.
