Code P114D MINI Description

The P114D MINI code indicates that the post-catalyst fuel trim via oxygen sensor system is too lean on bank 2 in the vehicle's engine. This means that the engine is not receiving enough fuel in relation to the amount of air being taken in, leading to a lean air-fuel mixture. This can result in poor engine performance, decreased fuel efficiency, and potential damage to the catalytic converter over time.
