Code P114C MINI Description

The P114C diagnostic trouble code (DTC) for MINI vehicles indicates that the post-catalyst fuel trim via the oxygen sensor system is too rich on bank 2. This means that the engine control module (ECM) is detecting that there is an excessive amount of fuel being delivered to the catalytic converter on the second bank of cylinders. This can lead to poor fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
