Code P2280 Description

The P2280 diagnostic trouble code refers to an air flow restriction or air leak between the air filter and the Mass Air Flow (MAF) sensor. The MAF sensor is a crucial component in the engine's air intake system, as it measures the amount of air entering the engine. This data is used by the Engine Control Module (ECM) to calculate the correct air/fuel mixture for combustion. When there is a restriction or leak in the air intake system, the MAF sensor may not receive accurate readings, leading to performance issues in the vehicle.
