Code P2621 MINI Description

The P2621 MINI code indicates a problem with the throttle position output circuit being lower than expected. The throttle position sensor is a vital component that monitors the position of the throttle valve, which controls the airflow into the engine. The sensor sends signals to the engine control module (ECM), informing it of the throttle position, which in turn adjusts the fuel injection and ignition timing for optimal engine performance.
