Code P2281 Description

The P2281 code indicates that there is an air leak between the Mass Airflow Sensor (MAF) and the Throttle Body. This means that there is a gap or crack in the air intake system, causing unmetered air to enter the engine. This can lead to incorrect air-fuel mixture ratios, affecting the engine's performance and efficiency. The MAF sensor measures the amount of air entering the engine, and the throttle body controls the amount of air that enters the engine. An air leak between these components can disrupt this balance, leading to issues such as rough idling, decreased fuel economy, and potential engine misfires.
