Code P114A BMW Description
The P114A BMW diagnostic trouble code (DTC) indicates that the post-catalyst fuel trim via oxygen sensor system is too rich in Bank 1. In simpler terms, this means that the engine control module (ECM) has detected that the air-fuel mixture after the catalytic converter is too rich, meaning there is an excess of fuel in relation to the amount of air entering the combustion chamber. This can lead to decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
