Code P114C BMW Description
The P114C BMW diagnostic trouble code indicates that the post-catalyst fuel trim via the oxygen sensor system is too rich in bank 2. This means that there is an excessive amount of fuel being injected into the exhaust system after the catalytic converter on the side of the engine referred to as bank 2. This can lead to decreased fuel efficiency, increased emissions, and potential damage to the catalytic converter over time. The vehicle's engine control module (ECM) uses the oxygen sensors to monitor the oxygen levels in the exhaust gases and adjust the fuel trim accordingly. When the system detects that the fuel trim is too rich, it can trigger this code.
