Code P114A MINI Description
The P114A MINI code indicates that the post-catalyst fuel trim via oxygen sensor system in Bank 1 is reading a rich condition. This means that there is an excessive amount of fuel being delivered to the engine in relation to the amount of air, resulting in a fuel mixture that is too rich. The oxygen sensor is responsible for monitoring the exhaust gases and providing feedback to the engine control module (ECM) to adjust the fuel mixture accordingly. When the oxygen sensor detects a rich condition, it signals the ECM to reduce the amount of fuel being injected into the engine.
Common Causes of P114A MINI
- Faulty oxygen sensor
- Clogged fuel injector
- Vacuum leak
- Malfunctioning fuel pressure regulator
- Issues with the air intake system
Symptoms of P114A MINI
- Decreased fuel efficiency
